Prestashop - re-design & add auction on web

Hello,

I want to finish an auction site on prestashop and modify the design of the site, put the auction system in place, add some features including that of checking the client's creditworthiness before placing a bid.

i really need someone serious. if not serious it is not worth it.

here is my site: http://biddingsport.com/fr/

and this is what i wish it would look like
