This would be a fairly constant stream of work. 15 pages of content (only 200 words) at no more than $2 per page. The 15 pages would be around one topic and I will provide the keyword for each page. So for example, a 15 page package could all be on Mustang Cars. page 1 would be 2007 mustangs, page 2 could be 2005 mustangs, page 3 could be mustang car parts, etc. Basically you could leverage your initial research to make it easier to write all the pages.
The person chosen should have a good idea of how to write to bridge the gap between sales copy and product info. This is what the pages will be like, a bit of info or a story about the product, and then subtle preselling.
You must have excellent english! I mean Excellent! Good work on the first project would lead to a steady stream of work.
