Website Content Writer - 200 Articles

I'm looking for a website content writer to produce 200 brief articles (400/500 words each): 100 articles on all aspects of debt and personal finance, and 100 articles on all aspects of fitness and health. Each article will center around one target keyword-phrase drawn from a list. I will pay $750 for the assignment plus a $250 completion bonus (that's $1000 in total = $5 per article). I expect the job to be done at a rate of at 10 articles/day. If the project goes well, I will consider extending it. I'm looking for quality articles, each should be original, well written, useful and very specific. Articles should be written for a US audience. Please, absolutely no copy-and-paste from other websites. Articles are to be submitted as individual TEXT files without formatting, just line breaks between paragraphs. One zipped file containing all of the articles is also acceptable. Articles will be used for my web sites as ghost-written content for someone else's byline. Applicable copyright laws must be followed since articles will be published as original content on my websites. If interested in the project, please email one sample article you have already written (preferably written for web). If I like it, I'll assign you the job.
