Website like Vistaprint

I need a webpage exactly like vistaprint.com. Rather than having tons of stationary items like them, website will only have 1 particular statonary item. The user will be able to login and pick from several different templates/designs. They will be able to customize it (insert text, insert pictures, move things around) just like Vistaprint. Their draft will be stored on the server and they can access it whenever they login to website. Website will have a shopping cart just like Vistaprint.
