Rock Concert Lighting Engineer

We are looking to hire a lighting programmer/engineer for concerts we hold at our Amphitheater in Norco, CA. We have about 20 shows per year. The design and install are already covered; I just need someone to work the lighting console and a few other other tasks during the show...
