Build a Website like eBay Charity

I would like to have website like Ebay Charity([login to view URL]) .And i prefer to use ReHub theme([login to view URL]) which i already bought from [login to view URL] theme provides Marketplace but not auction plugin,so we have to make integration with tHe plugin. Another critical difference between Ebay charity and rehub theme is: listing by [login to view URL],projects and campaigns has their own profile page and product profile page you can see which campaign or charity its for.(You can easily understand the system if you check ebay charity a bit.) Seller has to choose which donation will product be for. In Ebay charity you have option to choose what percentage of product will go for charity but our percentage is fixed so need to this option. I will prepare a opening one page my own so you can keep it very basic. To have little more idea by videos,check these: [login to view URL] [login to view URL] 1)Do you see any problem or any misunderstood point? 2)When can you deliver it? 3)Any question? Thanks for your interest and hope to work together.
