Membership directory plugin

Hi!

I’m looking for a plugin that will help my organization keep track of its paid memberships/subscriptions. It would be great if the plugin would allow users to subscribe via PayPal and send out alerts when a members dues are payable and allow the user to fill out a membership form with personal information and interests once they have paid. I searched the plugin database for “membership directory” but there wee no results. I was hoping, if there were none for free, maybe there was one the organization could pay a small fee for.

So, does anyone ever done this before, or have any suggestions, free or paid?

Thanks!
