design your own napkin script required Flash/Javascript/PHP

Hello. We are in a massive rush for this and need it ASAP We require a script that allows users to design their own napkins, very similar to this design: [login to view URL] However more efficient and streamlined... We do not require the design just the back end programming. We require more than just Napkins though, we have about 5 products we can print on... Please see the attached file for full details. We would require a few custom modifications such as: around about 8 colours to start with but I'd have to be able to add to the colours later on, Also I would need a custom colour button with a listing of custom colours and it would add $8 onto the price at the end shopping cart. Then I would have to have an option of what colour of print they want... of about 8 options, But I'd have to be able to add to it later on... The text would be a set size and not be able to be changed, and with positions I would have to have set positions that they can choose from a list. Also I only want a selected amount of fonts at the beginning, however would be able to add more fonts in time. On the checkout I would like a function for returning customers where it fills in all their details and also an option for a gift box, which adds a bit extra to the price. Ideally the script would be built in php, javascript or flash. for some more examples on similar products please go to the following sites: [login to view URL] [login to view URL] [login to view URL] I can supply you with all the documents apon request. WE REQUIRE THE SHOPPING CART PART OF THE SITE SETUP AS WELL.
