Moving the gear is actually pretty easy. I am 6'0" and about 120 pounds so if I can move it all myself, almost anyone can.
I have a good dolly that works upright or flat with all 4 wheels, and a 6x12 trailer with a ramp door. I have loaded in a rig like that by myself in an hour before, but I try to bring someone with me whenever I do mobile gigs to make it go smoother.
I talked to the owner last night about the stage setup for karaoke and he agreed about the trees with Christmas lights and some cardboard figures. We might do more stuff after that but I'm going for a baby step right now. I am going to try to find several strings of lights for each tree in different colors. When I eventually upgrade the rest of my light rig there I can put each color on a DMX outlet and have the trees change color with the rest of the lights.
