Booth is currently $500 an hour minimum of 3 hours.
He's also doing weirdo shit like tattoos by candlelight or blacklight now too. If you have an appointment with him, you have no choice but to go along for the ride.
He's also really big into collaborations. You can actually move up his waiting list alot faster if you'll just let him and two or three other guys go at it at once. You get to give them a general idea of what you want and they just do it, you are really taking a gamble on what it's going to look like but they all tend to look incredible.
I was on his waiting list at one point and there was like 2200 people before me the last time i called to check on my status. I'm probably due soon but i don't have the money to get him to work on me. I might just pay for him to sketch something up, which still isn't cheap but better than paying a minimum of $1500.
He's by far more known for his grey work, his color is good but it's not nearly as good as his greys.
