article writing in health niche

I need someone to write around 9000 words based on keywords I provide in a health niche. Your articles will be submitted to ezinearticles and other article directories so the requirement is that your article gets accepted by the directory if not I will require a rewrite to get it accepted. I will ONLY consider bids of $30 for this project. BUT, If you are a good dependable writer I can provide more work at a higher rate if I am satisfied. to consider your bid I will need you to answer the following question so that I know you are not just autobidding on everything that shows up here. 2 + 2 = ?
