Charity subs across multiple forums

[nicsnow]

Hello again (after a long absense), I need, if possible please a couple of pointers in setting up a payment means for subscriptions. The scenario is this: I have a charity I work for they have 3, let's call them, brands. Each brand is divided into 2 parts - paid for and public. The public bit they can register in and get on with it. The paid for bit needs them to register and then part with twenty quid and then have access to a 'green room area' with all sorts of nice stuff you can't get on the public area. Question is: is there a script or some application to write to a payment channel and then write to an sql db that issues username and password for the user? I.e. not a simple form that goes to a human being who manually enters the data (and might be off sick or something). Any comment would be greatly appreciated. Thanks.
