Shopify: shop setup + template modifications etc

BRIEF
We are helping a client launch a Shopify shop but unfortunately don't have the time ourselves at the moment. We are looking for a freelancer to give us a hand.

SPECS
- theme already purchased and installed
- domain name, shop name etc chosen and in place
- unlimited trial time to work on the dev shop through our Partner account (unfortunately that means you cannot use yours)
- all product photos and descriptions will be provided by the client this/next week

TASKS
1. Finalise the shop setup, fine-tune all the settings so that the shop looks more or less exactly like the template demo (we'll provide the link etc)

2. Include the client's Logo + bran colours, plus ongoing minor modifications to the look & feel (based on the client's feedback)

3. Modifications to the templates code:
- ability to embed external images/files in place of one of the product images
- a new field on the product page ("Get the look") where products from the same "look"/set will be displayed
- perhaps one or two more tasks - tbc

TIME FRAME
- we are looking to start ASAP
- most of the work should be completed by end of next week (22nd)
- then ongoing support/modifications and so on - until at least the end of December

REQUIREMENTS
- you need to know Shopify inside out: from setting up shops to customizing themes, from working with Apps to developing new theme features using Liquid
