card design annimation

Hi there, my company makes credit card designs for my clients, i would like to provide my clients with a link where they can go and view their card design. so basically i need a system which creates annimated card designs. I need a small application that lets me enter a jpf file of both the front and back of a credit card design and then the system would output a file of an animated version of the card specified - so that it can be flipped back and forward by my client. simples.
