Ajax and PHP Drag and Drop Shopping Cart

No website needed. Bascially I need a drag and drop shopping cart that is a mirror of the one at [login to view URL] I believe they are using Dynacart as the payment gateway but if you have a better and/or easier one to integrate that is able to update the inventory automatically, etc... let me know. Bascially what necessary features I need are: - same front end as panic but the ability to load new items in a section as I choose. No need for categories or individual pages for the products I will just use Anchor links from other pages to go to a specific product area. - same options as panic with the sizes and quanity options on the front end because I will have popup slide shows with the models wearing the specific size shirts to illustrate. - Backend~ I don't know the exact specs for the backend of the panic cart but again I just need it to be easy to update or upload a new products, images, prices, etc... and the payment gateway should be able to update the inventory as necessary. Thats really it. I had some quotes previously but again I would love to see what you can offer if possible. I know that [login to view URL] offers the script for free and the instructions to do so [login to view URL] Basically the funtionality is the majority fo the work.
