article writer needed ASAP

Hello everyone!Looking for an experienced article writer with a good knowledge of SEO to produce articles on an ongoing basis. I am looking for someone to establish a long term collaboration with, since I have a lot of work to provide and I have no time to do all of it. Every article must be well written, 100%original and error free. Initially, I will need someone who is able to deliver 4 500-worded articles per week, following the keywords I will provide you. Fast turnaround and fluent English are necessary. Please do not bid more than 1,50$ per article, since I am not allowed to pay more than that. I can pay you via GAF or Paypal, as you prefer. Thanks and happy bidding!
