I like your service and I am interested in seeing if it would be a possibility for me. I am developing a site that will allow users to sign up for a wedidng website for 1 year or 2 years. So I am not selling a downloadable product or a tangible item. Would your service be a good fit? I would need to be able to pass parameters after the purchase as the user would go from a free trial to a year of service or 2. This seems feasible from some of your examples. Also, I have a Paypal Paymet pro account. How seamless would the process be? Meaning, I wouldn't want the users to go to an ejunkie page . . . Hopefully they could stay on my site during the whole purchase process. Is this possible?
