I have been working with ASP based carts for 10+ years, hosting them on Godaddy for ease and using MYSQL databases.
I can forward more details pending more information about your needs and expectations.
I have used ASP cart as the basis for my implementations, which is a good starting point, and then customized as you may or may not be required.
The cost of such an implementation is far more then your posted value, and if you have real business to explore this is soemthing to be negortiated upfront for both costs and time/materials, depending on what you can do or not do yourself.
