professional writer to research,develop and write the content for Anazon A+ Pages/EBC Pages

We currently have a wide range of products that would be too costly to have someone do the job for us. What we need at the moment would be a good writer that understands how to research items that are already selling well, but has to be optimized in order to get them to the next level in sales. Candidate should be able to write good listings, and design the A+ Pages/EBC Pages
She'll have to design the pages, and give ideas of what the images should look like. The actual photographer and editor (Photoshop kind of work) would be somebody else.
