Online Font Preview tool

The biggest portion of my web site ([login to view URL]) is dedicated to making customized pet tags. I often get requests from customers to see what their pet's name will look like in their chosen font. I'd like for them to have an online tool where they can type in their pet's name, select the font from a drop-down menu, alter the size, then view the pet's name in the font they selected. I found one here that is almost exactly what I'm looking for: [login to view URL] I would like to have control over the files, so I can add/remove fonts as we change our lineup. I can upload all of the TTF files and the script file(s), as long as I know where to put them so they'll work together properly. I'd like to spend $50 or less to have this done. As an alternative, I'm also wondering if it's possible to have a script set up that would allow the customer to preview the completed tag. In other words, if they selected a large bone (shape), dots (background), with "Fluffy" (customer types this in) using Curlz (font), they could see a preview image of that particular combination. I'd like it to allow them to make a change by simply making a different selection from the drop-down menus, then hitting a 'preview' button. I can create & upload all of the size/shape/background images that I'm assuming would be necessary to make this work. I'm a small home-based business, so I don't have a large budget for this, but I would like to get some bids on this project, as well.
