Articles on Web promotion and email marketing

Hello Everyone, I am looking for writers who can write 500 word articles everyday regularly. This is an ongoing project and I am looking for serious bidders only who can work for next three months continously (7 days in a week). Please don't bid if you can't commit yourself for long-term works. The articles will be assigned everyday to the selected bidders. Payment will be done by paypal at a regular interval. Very Important- Please don't bid if you are expecting more than 3$ for a 500 words article. Please support your bid with a sample of atleast 3 paragraphs in length. While placing your bid, convey us your favorite topics. How many articles you can produce in a day? Thanks, Jay
