Modify TagBot Template to work with eBay listing app

We have a TagBot template that we wish to slightly alter. Currently, images have to be uploaded to a server then links changed in TagBot. We want to be able to upload our images via eBay listing (like normal) and display them within the description (thumbnails on the left and larger image to the right) The larger image should change as each thumbnail is clicked (to display the thumbnail larger) We want the listing Title to automatically populate within the description. The price should also auto-populate (as we fill out the eBay listing) Also, if possible, we need the "Buy It Now" links on the template to actually "Buy it Now" for the item. Also, at the bottom of the listing (Under "Info") is an icon of a home. We want the icon changed to an icon of Texas. The changes to the template MUST meet current eBay rules for listings (no active content, etc.) This should be a fairly quick and easy job for someone with the right skills.
