Professional copywriter for t-shirt listing (Amazon MBA and Spreadshirt)

I am looking for an admin assistant for my t-shirt business (Spreadshirt and Amazon MBA).
You are responsible for the listing content. That means to create for each t-shirt design:
- 2 different bullet points for the MBA Listing, it must be written in coherent sentences and include 10-15 keywords from the niche; each bullet point should have more than 250 letters
- 10 – 15 most relevant keywords for this niche or t-shirt (For Spreadshirt and Amazon MBA)
- 1 description for the Spreadshirt listing, it must be written in coherent sentences and include 5-10 keywords from the niche; the description can be maximum 200 letters

To get this info you must have a research tool like Merchinformer or Merch Titans. Roundabout I have 200 t-shirt designs per week to do.

Please do not apply if you are not high experienced in this kind job. I will pay per listing set. Start could be ASAP.
