Etsy Listing SEO Optimisation for Google Search Rankings

I run a natural wellness shop on Etsy called NaturesOasisUK selling Ethiopian black seed oil, black seeds, and raw honey varieties. I currently have 20 active listings and I need all of them optimised for Google SEO so they appear in Google search results, not just inside Etsy.

This is not just Etsy internal SEO. I specifically need someone who understands how Google indexes Etsy listing pages and can optimise accordingly.

The work involves:
For each of the 20 listings I need the following done:

Keyword research using a tool such as Google Keyword Planner, eRank, or similar to find the best phrases real people type into Google for each product.

Rewrite the listing title so the most important keyword appears in the first 40 characters.

Rewrite the opening 150 to 160 characters of each listing description so it reads naturally, includes the main keyword, and works as a strong Google meta description.
Rewrite the full listing description body so it answers buyer questions and is written in a way Google rewards.

I am also adding new listings on a regular basis so I may need ongoing work beyond this initial batch. If you offer a good service I would look to build a longer term working relationship.

What I need from you before I hire:
Please pick one of the following products and send me a sample rewrite of the title and opening description line as part of your proposal. The products are Ethiopian black seed oil, Ethiopian black seeds, or raw Spanish honey. This shows me you understand the brief before we start.

Budget: Open to proposals. Please quote for all 20 listings as a fixed price.

Timeline: Looking to get this completed within 2 weeks of starting.
