eCommerce Online Store using ASP.NET 3.5 with SQL backend

We would like to have a similar site as below having e-Commerce functions i.e. shopping cart, order management, payment management and invoicing in it. [login to view URL] This needs to a portal style site which should be purely DB driven including CMS features, if needed. We would like to hear from those bidders who have actually already worked on ASP.NET based eCommerce online stores earlier. Please include your work/project samples while bidding and also consider the "budget range" as mentioned. Two Deliverables: 1. Complete ASP.NET using C# Code (including backend code/schemas) with ownership given to us. Note: There are already few such open source eCommerce .NET applications out there but here we want to own the code which should be delivered to us by you as part of this deliverable. 2. Design and deployment document.
