Im looking for a script where hosts can sign up and receive hosting requests from people looking for hosting. It would be something like hostvoice, but it would be free to all hosts.

Anyone have any ideas on what I could use?

Don't know any off hand. You're best bet would be to check www.hotscripts.com or get something custom done.

You can find the script that is you are looking for on http://www.scriptsfrenzy.com/hostdirectory.html Good luck.
