Online ticket, gift voucher script (for OSCommerce) PHP guru needed

Printable Gift Vouchers Context: I want to sell "printable" gift vouchers & "entry tickets".? Each voucher will have a unique ID so that it can be checked and redeemed at entry. A PDF file created automatically? for each on-line voucher. Customer can print this voucher. Front end: From OS Commerce's point of view, it will be just another product. The product will appear in shopping cart. Customer will purchase the product, choose a value (attribute), and pay for it. *(Note: I prefer using OSCommerce but I am willing to listen to your recommendations. If there is another shopping cart that will serve my purpose better, or if you can custom make one,? then that would also be fine).* Back end: How do you do this in OSCommerce? I found a gift certificate module but not sure if it's enough. I think this is what I need in backend: **Products -> Add Products -> Add Product type -> gift card** For gift card: - gift card name - voucher number starting number - voucher ending number - length of code (6 chracters, 10 characters etc.) - any custom code generation rule: for eg: alpha-numeric, or just numeric - how many max vouchers to generate of this type every week or every month? - bar code configuration - graphic/template to print on voucher - allowed values (same as product attributes): 5, 25, 50, 100 - price: - sale price: -bar code rules? **Products -> Add Products -> Add Product type -> event ticket** - event name: - event details: - event date and time: - how many tickets to sell/how many seats available? - a method to display seats/tickets and specify pricing for each type of seat *** This way, **I want to be able to sell both tickets and vouchers online** OsCommerce.? Finally, I need a simple **admin-page**, where you can login with vendor_username, and verify and view all generated tickets. You can mark tickets as used, cancelled, refunded. Thanks
