Phone/Calling card site

This project is to build Phone card e-commerce website to sell instant pins for phone cards using online payment gateway. The reference site : [login to view URL] We are open to use any readily available third party scripts (PHP or ASP), also we are open to choice of OS (Windows vs Linux). Key features we are looking are : 1. Processing credit cards online and providing instant pin to the user 2. Admin panel should have selection of cards. 3. To simplify, users can only call to 'France' (default, but Admin should be able to change), Call From can be any country. 4. Admin panel should be able to 'add' or 'delete' cards 5. Admin panel should also able to 'hide' the card details, if required. 6. We are also open for DB (My SQL vs SQL DB) 7. Registered users should be able to saved in the DB (optional) 8. SSL for Credit card processing (optional) Example : Calling from USA to China, if there are 5 cards available, Admin panel should be able to default the search to one card, the card details (logo etc) should not be visible to the end user May need ongoing support for developing the complete site. While bidding, let us know if have done any similar projects along with link to the demo sites, time required for completion and most importantly, the name of the script (if third party) used. Pls take a look of the above key features. This is an urgent requirement and the developer may need to work ASAP.
