Bid and order tracking system for Engineering company. Looking for SQL back-end and web based front-end.

I am a consultant and I have a client who needs a custom Bid and order tracking system. The also need the ability to set up reminder emails for each process of a bid as well as general reporting regarding the history of bids and projects. We already have a Windows 2003 server with SQL 2008 installed. I will be working directly with the programmer to provide technical details as well as testing completed work. This is a B to B project. You will not have to deal directly with any end user. Part of the project has already been developed, but the programmer was unable to continue the project due to personal time constraints. You can continue the existing work, or start with new programming.
