Is there such a template?

Hi there,
Im searching for a template if it exists.

We are wood fired oven manufacturers and we need a site that customers are able to construct online the oven they want with all our components listed. Like a flowchart.
A visual click and drag option would be nice and at the bottom of each page a running visual image of what they are purchasing. The items from the selections would have appropriate prices updated as they progress threw the pages and add the new components.

If there is such a template can anyone point me in the right direction. Thanks Gareth
