Facebook Shop App

I hav a project to make a Facebook App 'My Etsy' like the etsy shop app example here: [login to view URL] I need a facebook page to add the app and then the my xx shop tab appears - i want to make a web cms on our server to provide the products to show in the shop - the products pulled from a database I can do the design - just need the code doing - ideally in VB ASP any questions ask need quickly - will pay more for a quick turnaround
