eZine articles needed!

I'm the webmaster and creator of an online ezine for aspiring teen/tween/twenties models. I need people to write articles on a regular (monthly) basis, based on whatever the assignment is for that month. May include multiple assignments each month. Topics include fashion, music, self-esteem, health and fitness, and many more. All authors will receive credit for their work, as well as their own page on the website highlighting all their articles, and can be used as a promotion tool for their own freelance writing careers. Once the site is fully up and running and making money, there will be some small forms of payment, but for now payment will ONLY come in the form of free advertising and promotion. I am an SEO specialist, and can guarantee traffic to the site... it's just a matter of needing others to create the textual content. I'll also be happy to help evaluate your own personal sites for free if you like. This is set to be a long-term partnership with repetitive short-term deadlines... please do not bid on this project if you're expecting immediate financial compensation!
