Looking to modify an open source proxy script so that we can have people browse for free for XX amount of pages per YY hours/days, and then ask them to upgrade to our premium Proxy service for $ZZ via Paypal at which point we will grant them access (automatically) to unlimited use for AA days/weeks/months or whatever they paid for. It will be done on subscription basis and when subscription runs out their access will be revoked etc. This should make use of PayPal IPN if possible
