I think most people here are recommending you run from this project, in its current form. HoW jobs are fraught with danger: the high school AV club kid who often runs things and the unknown of who will show up with what source device on any given day. If they can't afford to do it correctly, pass...unless you don't enjoy your Sunday's (and many evenings) off. Doing a HoW a "favor" won't get you into heaven, but it will shorten your life-span.
