Ah, thanks Tim. I also found these guys: Artist Representation and Management - Roster which have the bands I mentioned as a matter of fact.
We're almost a one stop shop! For several events I have booked the act, made the radio commercial for the show, made hotel/food arrangements, bought food for the bands at Wal Mart at 2am the night before, and did the sound and lights
As many of you know this is especially helpful in small towns where you will often be approached by someone that says, "here is our budget, make a concert happen!"
