Didn't know what to call the title but I have a question involving money. I'd like to set up a small service for people on another site that only supports PayPal for their VIP.

Now.. The service would be, I take X amount of money in a form, such as a PSC and then give you a gift voucher that lets you buy VIP. But.. I am wondering.. How can I trade the cash on the PSC back to my PayPal?
