Silver Light Business Card Design Tool

We need to integrate a component into a website we will design. We're developing the web application. The component we need should work like the one on: http://www.buildasign.com. Click on: Signs , then yard signs, then click on any template. You will see a silver light component that allows the user to make changes to the card template. It should allow saving, sending to a friend, generate a PDF for printing. I'm assuming each template will have some source where it can be loaded to the silverlight component when selected. We need a re-usable component, So we need to be able to define templates for it.
