I was thinking of getting a sort of user membership/credit backend system done. I think most of these types of things are dome predominantly in php? I would basically create an account for a user (email/password), They login to their account and they can purchase "credits" with paypal, once paid they would automatically receive their credits, and have the ability to spend them on whatever i am selling. I would have the ability to alter what the ratio of credits : services is, on the fly. I would also have my admin panel that would show all "orders" in my required format so that i can work on them. That would be the main gist of it, with various other functionalities implemented. I'm not sure what such a task would be "called" formally, but its along the lines of what i'd be interested in. Any ideas on how much this sort of script would cost, and how long it'd take? Thanks.
