looking for script to display/sell templates

Hi-

Hope this is in the right area.

I am looking for a script that will allow me to display
and sell original website templates.

Ideally it will show a group of thumbnails of the templates, and then
the user can click on one to view a fullpage version.
If they like the template they can automatically purchase it
and download it immediately.

I've looked in hotscripts but couldn't find anything...
anyone know of one?

Thanks in advance.
