Well you are in luck, I was hired by a company to develop almost exactly what you are looking for. I did it using Mambo, which is a free content management system. In addition, I had it plugged in with paypal for monthly based recurring subscriptions. And it worked! Unfortunately, the company changed gears and I had to take the site down. You will have to email me to view the site because this website is not letting me post links. I figured out how to put this all together with no money (well, they paid my salary). If you like, I could help you out... email me at
