Fix online ordering system, asp.net, C#

We took over the development of a partly done ordering system for a client. This is NOT full blown e-commerce. Just a way for clients of a printing company to order business cards and a few other products. The billing is done seperately, so only an order is generated, no payment is processed. Some stuff doesn't work. I'm not sure what all is wrong and I don't even know how to estimate the time involved. I am willing to pay on an hourly basis after the initial bid amount is depleted. The customer is www.actionprinters.net. The online ordering system allows an admin to add new customer accounts, edit login info, add products & images. The client can select items to order and provide additional details as required before submitting their order. Further details are available upon request, including the current source code. We will place a high emphasis on your past RAC ratings. I need immediate availability and coders should be highly experienced with ASP.net, C#, and MSSQL database engine. Code written should be will documented, although I can't promise what we have now meets those standards. Some rewriting of code may be required. When placing your bid, be sure to indicate how many hours are included. We will pay for more hours if the tasks cannot be completed in the alloted time. I can provide access to the current code base for review if needed. Please ask. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
