"Your English skills must be excellent"<---check (ask me to write a sample - of a product, or two, chosen by you - and I will prove it; wouldn't want it any other way)
2. Each description should be about 150-200 words"<---got it.
3. "Good quality, keyword rich content with SEO in mind"<---have written 700, or more, SEO articles, and a lot of articles completely focused on quality, so it's not a problem.
4. "No copying other websites, we do have systems to check"<---no problem - I love to write.
5. "Total of 100 descriptions to begin with"<---sounds great.
"knowledge of SEO and adult products"<---in regards to the latter, I know women; so writing in a way that inspires them sexually (read: helpful when advertising adult toys) is second nature.
The bid is for 10.000 words. Let's start.
