Best Theme or theme(s) for selling licenses for something

Hi there

My client has a business that sells certain types of licenses in the sporting industry. These licenses cost a lot of money and thus the actual purchasing of the license cannot happen online.

However, the client would like to have a “marketplace” where such licenses can be posted and then for interested parties to put in offers or possibly even pay a deposit to hold the license. Ideally would like a theme that would make this type of “ecommerce” site work well as it is not the typical buying of a product.

If anyone can reccomend something to be able to list products (in this case licenses) that people can make offers on and then send in inquiries. The purchase would be done offline as there is a extensive documentation required to complete a sale. The website is solely to advertise what is available and what is not.
