Writing Website Content

I am looking for a writer that can write contact for a 20 to 30 page website. A few of the main pages will be written by us, but there will be at least 20 to 30 pages that need to be filled in. The architecture of the site is set so a topic for a particular page will be given and 500 to a 1000 words of relevant content must be written. Using information from other like industry sites is fine as long as it is not blatant plagiarism. Ideas are free. There is plenty of relevant information available on the web The research involved is minimal. I am looking to pay in the $10 range per page, and I will agree to a minimum of 10 pages for the first order. If the Freelancer we select can actually preform the task then we will contract a minimum of 20 more pages. If you have done work like this please include a link that will be helpful in making our decision.
