Theme needed that's like e-commerce, but Buy Now buttons are "Make Enquiry"...

We are possibly creating a website for someone that is where you might hire out an item, but not buy it. So you see all the items like you would on a goodchild type theme, but where the Buy Now button is to request information with a view to hiring it.

The button takes the user to a forum, the forum now knows the product you are enquiring about, and perhaps a calender to select a “from and to” period, and it either goes to a database, or out via email (or both).

Does such a theme exist?
