Writer/team needed for a long term project

I need urgent writers or team for a long term project. Writer/team must be able to deliver 10+ articles per day. He must have copyscape premium and all articles should be checked and re-checked before delivery. Copied content will be rejected directly. The grammar and sentence usage should be correct. I won't like fancy writing or verbose sentences. The English used needs to be simple & clear. The information should be written in such a way that it actually helps the user. Only experience content writers should bid. It is essential that the writers have an understanding of SEO. I do not want keywords stuffed and excessive use, but they should be used in such a way that the article is pleasant to read as well as it contains keywords for SEO purpose. Please write a sample article on immigration with in 200 words. I will pay $1.25 initially for 500 words. This will increase with the performance.
