Article Writer Needed

I am looking for one good dedicated writer to write articles on weekly basis for me. Currently I have a need for 15 articles weekly on dentistry. 300 - 350 words/ USD2 each article. The articles have to be originally written (I check every one of them), interesting to read and error free. Deadlines are very important. The initial project is on dentistry but this could change. I prefer writers from India however if you can work according to the guidelines and budget mentioned above, then it does not matter where you are from. Please submit a sample of your work for my perusal. You should be able to start immediately and accept payment via paypal. Please apply only if you are serious. Thanks
