Our church used to also rent a hall for about the past 6 years. We had our entire setup mobile. The trick is to make evrything user friendly for setup and tear down. We had a bank of 8 amplifiers running our mains, and 4 sets of monitors, full band (including guitars, keyboards, drums, and other percussion) as well as wireless mics and the standard stage production stuff. Just before we moved to our new location, we had the whole thing so simple to setup I had two kids in grade 4 doing most of it for me.
