Create additonal wholesale Prestashop Theme

Scope of work. I have recently created a new version of my shop running on prestashop 1.4.1. A new theme has been created which covers retail customers. I need to have an additonal theme created that allows my wholesale category to look like the attachment. So I am not sure if two themes can run on the same shop or how to achieve my goal. But that's what I need. The wholesale theme is the same as the current theme other than a wholesale customer can select the quanities on one page without having to go into the details page. I will be providing the updated details page which will be standard except no sizes or quanities. Deliverables is one wholesale category page and one details page for the wholesale category while the normal retail theme remains. Payment will be loaded into escrow and only released after the successful implementation of the new theme that provides what I need for retail and wholesale customers as per my scope. Please put "The moon is square" in the your response to show you have read the scope.
