We had an Ad here that wanted performers to "audition" for her before she would book them. A real scam - that is all she ever did - free entertainers for as long as there was someone stupid enough to fall into the trap. Most of these AD types don't last long around here though.
Anyway, now most of my gigs are folks who call me and I don't really have to make many calls until an AD leaves - then it is like starting all over at that place. I have never made personal visits because the ADs are seldom available - nor have I sent CDs or other materials. Once I sent a CD and could never get booked and later found out they were playing CDs sent by entertainers rather than book them.

I should have said that's it's best to call first to make an appointment with the AD so you don't interupt any activity or meetings they may have.
I'm sure there are some unscrupulous AD that would take advantage of a free audition. It doesn't concern me much because I have have a good full time (non music) job... Playing local entertainers CD's rather than booking live music or at least buying CD is pretty low. There lots of really good and inexpensive used CD's available. Anyways Hammer is right about when an AD lives it's just like starting over.
