Content Writer -30 pages

I need 30 new pages of content written for two web sites (a loan web site & a herbal supplement site. You will be given the keyword(s) for each page, and the keyword density that should be attained. Each page should be about 500 to 600 words. Writer must have excellent English writing skills. No spelling or grammar mistakes. Each page must be unique (no copy and paste from several sources, I will check them using Copyscape). Please provide at least 3 samples of your previous writing (similar project). Once payment is completed, you agree that I will own all rights to the content, and that you should never use or post it anywhere without my permission. I am willing to pay only $50 for 30 pages and must be done within 10 days. This is not sales copy, just informational articles like you would find on ezinearticles, so please keep that in mind upon bidding. Thank You
