Articles to be written daily

I have approx 50-100 articles to be written weekly. I would like excellent writers for this project. You will have to research the topic and provide 500 word articles. To start this project I will be paying $1/article if after the first 2 weeks the articles are good and delivered on time and free of spelling and gramatical errors, I will give an increase. If your interested and believe that you can provide the service then bid. I will be looking to for 5-10 good excellent writers. All documents must be written in American English and be free of spelling and gramatical errors. You have to do the research and provide the article or articles back to me as soon as its done. This will be an ongoing project. Probably upto an year.
