My insurance is through Performers of the U.S. There's some controversy about their mandatory safety course but it's not really that big a deal. Get insurance before you do the show.
I use the reliable and easy to use Virtual Soundman iCue2. I bought three before Kelly went out of business. Before the iCue2 I used other Virtual Soundman products. Never had a problem.
I happen to serve as the Mountain Region (incl. NM) Lead for "World Hypnotism Day", and I'd love to connect more with you around that. Check out the URL: www.WorldHypnotismDay.com Even though the actual date is Jan. 4th every year, the site is up all year long and has some great stuff on it. Sign up, and they'll send you some freebies!
