Add post sale functionality to my website

I need a sales certificate to be created after someone purchases a daily deal though PayPal and then returns to my website. This certificate needs to be e-mailed to the business e-mail address for the specific deal. The certificates should be printable from the members account admin panel. I also need the urls to be updated to display the page name instead product id's: Example - [login to view URL] I want the 606 to read: Tacos Marquitos. Have max. budget set aside but project to be bid by hourly rate.
