Looking for any software, either commercial or open source, that would run a "get quotes from local contractors" type of site.

Please, the future of the civilized world depends upon me finding one.

Check out hotscripts.com

can you give a few more details? How does someone submit for a quote? How do contractors deliver their quotes? etc.

If by chance you are looking for a custom script, send me a PM... I am close to finishing the projects Ive been working on, so I am keeping an eye out for new clients.
