Change user font dynamically

We manufacture products that we need to be able to allow the user to view the way there text will look before purchasing. A sample of what we want is located here: [login to view URL] This is not our site. We are looking to be able to perform what happens in step 2 and step 3 and then hitting the preview button. We run a shopping cart program and we don't want it directly incorporated into the cart rather a "stand-alone" script that we could place anywhere on our site. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
