@AnswerMan- I was part of a community theater for several years, and we managed to pull off some very professional productions with a shoestring budget. But you're right about finding motivated volunteers with skills. Our main director was also trained in theatrical lighting and sound, so he took care of a lot of the technical things. He moved to a larger city a few years ago, and there really hasn't been anyone with the skills to take his place. We do much smaller projects now.
I'm always amazed whenever I attend a theatrical production in a large city. Everything looks completely professional, and they can do things on a stage I never thought possible. I saw a play about Buddy Holly, and at the very end, a bank of bright lights flashed at eye level. By the time I could see again, all of the actors were gone and a single guitar was onstage. It was like a magic trick.
