Registration code generator redirect as a product

I have a php-generated form that takes user input and generates a registration code (based on our own algorithm) and emails it to them. This code is used for some software we sell. My desire is that the user purchases the code as a product and is then redirected to the webpage while hiding the URL to it

Anyone know of a way to do this within OC 2.2?

I am willing to pay to get this extension!
