I was looking at Bricolage, however it appears to be more suited to text content publishing. I currently use Template::Toolkit to print out the bids and I imagine I could do all the programming myself--naturally, it would be helpful to find some package that suited at least some of my requirements..
If you want to keep using Template Toolkit with some extra support for common things like sessions, users, etc., take a look at OpenInteract.
