I am looking for a reliable, long-term Thumbnail Designer to create high-CTR thumbnails.

What we need: - Niche: Fragrance, fashion, luxury lifestyle. We need a clean, premium, high-end aesthetic (NOT gaming, NOT over-edited neon styles). - Volume: ~10 videos per month (~30 thumbnails in total) - can be more - Process: I will provide the raw screenshots/assets and the 3 conceptual directions. You will deliver 3 high-res JPEG variations. - Budget: $15 per individual thumbnail ($45 per video set of 3) but give me your price you expect for one thumbnail.

Shopify CSV product data specialist

This is not a Shopify development project. It is a focused product-data audit and correction job. I already have the Shopify product export and official supplier CSV feeds. The work is primarily comparing the datasets, correctly mapping the specification fields and safely applying the required corrections. An experienced Shopify/CSV/SyncX specialist should be able to complete this efficiently. I am not looking for someone to spend days developing a custom solution. However, accuracy is critical. I have previously had a freelancer incorrectly upload product specifications, so I require a 10-product test and my approval before any bulk changes are made. I need an experienced Shopify product-data specialist to audit and correct the technical specifications of approximately 500 products on my Shopify lighting store. I have official supplier CSV product feeds from three suppliers: • Endon Lighting • Elstead Lighting • Impex Lighting The supplier CSV files contain the correct product information and will be used as the source of truth. The main objective is to compare the supplier data against my existing Shopify product data and identify any incorrect or missing specifications, then safely correct the Shopify products. Products should be matched primarily using the Variant SKU. Specifications to check include dimensions, height, width, projection, diameter, weight, finish, colour, material, bulb holder, bulb type, number of lamps, maximum wattage, voltage, IP rating, class, dimmable, LED information, lumens, colour temperature, energy rating and any other relevant technical specifications contained in the supplier feeds. SyncX: Stock Sync is the preferred method for carrying out the updates. However, if you believe a direct CSV comparison using AI/ChatGPT/Claude and a corrected Shopify CSV would be safer and more efficient, please explain your proposed method before making any changes. IMPORTANT: I previously had a freelancer upload incorrect product specifications across my store, so accuracy and controlled testing are extremely important. NO bulk changes are to be made initially. The project must start with: A complete Shopify backup. A test using approximately 10 products. A before/after comparison showing the existing Shopify value, supplier value and proposed correction. My approval of the test before proceeding with the remaining products. The three suppliers should then be processed separately: Endon, Elstead and Impex. DO NOT change or overwrite my SEO-optimised product descriptions, meta titles, meta descriptions, collections, handles or images. Only the agreed technical specification fields should be changed. If a product cannot be confidently matched to the supplier SKU, it must be flagged for manual review rather than guessed. I expect the successful freelancer to provide: • Completed specification audit • Corrected product data • Excel report showing all discrepancies and corrections • Documented field mappings • SyncX configuration, if used • List of products requiring manual review • Confirmation that no unauthorised fields were changed I am looking for someone with genuine Shopify CSV/data-mapping experience, Shopify metafield experience and preferably previous SyncX: Stock Sync experience. Please tell me: Have you used SyncX: Stock Sync before? Give me a specific example. How would you compare 500 Shopify products against three supplier CSV feeds? How would you ensure that descriptions and SEO fields are not overwritten? How would you test the first 10 products before doing the full catalogue? Would you use SyncX, direct CSV/AI comparison, or both? Why? What is your fixed price and estimated completion time? I am happy for you to use ChatGPT, Claude or other AI/data tools to make the comparison faster, provided that the supplier CSV is treated as the source of truth and all proposed changes can be demonstrated before being applied. Accuracy is more important than speed. I will not authorise a full catalogue update until the initial test has been checked and approved.

AI Character & Video Specialist – LoRA / Consistent AI Model

We are looking for an experienced AI character / AI video specialist who can work with an existing AI model identity and maintain a highly consistent character across images and video. This is not a basic AI video generation job. We specifically need someone who understands LoRA-based character consistency, reference workflows, identity preservation and AI video production. We already have an AI model/character and may provide an existing LoRA file. You must be comfortable working with an existing LoRA rather than requiring us to rebuild the character from scratch. The goal is to create premium, highly realistic social-media and campaign content where the same model remains recognisable and consistent across: different outfits different locations different poses close-ups full-body shots lifestyle scenes cinematic scenes multiple videos Facial identity must remain stable.

We care about the final quality and your understanding of character consistency. Important We already have character assets and may supply: existing LoRA file reference images character/model images visual direction example environments clothing references You must be able to inspect the existing material and tell us whether you can work directly with it. We do not want someone who automatically says that a new LoRA must be trained before even reviewing the existing file. If the existing LoRA genuinely needs improvement, you can recommend that after testing it. Paid test We will begin with a small paid test. For the test, we may ask you to create: 2–3 consistent still images using our existing AI character / LoRA 1 short video clip using the same character The purpose of the test is to evaluate: facial consistency realism character identity preservation motion quality clothing/environment control ability to work with our existing LoRA If successful, there is potential for ongoing work creating regular AI model content. When applying, please answer ALL of the following: Have you personally worked with LoRA files for a specific human character/model? Can you work with an existing LoRA file supplied by us? Which base models do you normally use with LoRAs? For example: FLUX, SDXL, Stable Diffusion 1.5, etc. Which workflow do you use for maintaining the same face and identity across multiple images? Which workflow/tools do you use to maintain the same character in video? Please send 3–5 examples showing the SAME AI character in different images or videos. We are much more interested in consistency than random beautiful AI images. Please clearly state which parts of the examples you personally created. Can you maintain the same character while changing: clothing location pose lighting camera angle Can you create both: realistic still images realistic video clips Which tools do you personally use? Do you work locally / through ComfyUI or mainly through web-based AI platforms? Would any part of the work be outsourced?

Please start your proposal with: LORA CONSISTENCY so we know you have read the full brief. Please do not send a generic AI portfolio. We specifically want to see the same character reproduced consistently across multiple outputs. If your portfolio only shows different AI models in every image, this is not the right project.

Chartered Geotechnical/Civil Engineer desk-based verification

A residential development in the South East has completed its foundation piling — thirty bored piles into chalk. The planning permission requires a verification report by a suitably qualified engineer. We are looking for a signed statement, one to two pages on your own letterhead, giving your professional interpretation of the completed records on two questions: Do the integrity test results mean/demonstrate that the installed piles are sound? Do the monitoring records demonstrate that the works caused no adverse ground or structural movement? Your opinion would be based on the documents already produced, which we will provide in full: low-strain integrity test results for all thirty piles, the complete structural movement monitoring log, the original geotechnical assessment, the approved construction method statement and the piling contractor's method statement. You are entitled to rely on the factual data in those reports — the survey measurements and test results — as accurate and complete. The judgement as to what that data demonstrates is yours. Requirements: CEng or CGeol chartership with membership number, and professional indemnity insurance covering a signed statement to a planning authority.

Help to check and develop a web app

We have built a small web app and we want an independent technology professional and app developer to check it over, fix what the check finds, and then look after it. We are not asking anyone to rebuild it. We are seeking two things: your costs, and your approach. Tell us what you would do, in what order and why, as well as what it would cost. We have not set a budget and we are not looking for the cheapest quote. We are looking for the supplier who understands the job. What we want you to quote for Please price each of these separately so we can compare quotes, and say clearly what is included and what is not. With each one, tell us briefly how you would go about it. A. Code and security review (fixed price) • Read the source code and tell us what is wrong, badly built, or risky. • Look at the access code. We know it is a turnstile rather than a lock. Tell us whether that is reasonable for a free tool, and what a better option would cost. B. Testing on real devices (fixed price) • Test on current and older iPhones and Android phones. • One behaviour matters more than any other: when a builder taps the report link in an email, does it open the app they installed on their home screen, or a separate browser window that cannot see their records? Tell us what actually happens on each platform and what we should do about it. • Also check adding to the home screen, working with no signal, and the camera and voice dictation. C. Fixing what A and B find (price or day rate) • We expect to agree the list of fixes with you before you start. • Quote a fixed price if you can, or a day rate with an estimate. D. Keeping it going (annual price) • A few days a year: small fixes, the yearly access code change, and updates when the Code changes. • Tell us your response time for something broken, and how we reach you. E. Optional, priced separately — tell us if you would recommend it • Putting the app in the Apple App Store and Google Play. Note that it already installs from the browser without this. • A small server so customer reports arrive automatically instead of by email, and records are backed up off the device. This would mean we hold customer data, which is a decision we have not taken. Price it, but do not assume it.
