Tough spot. Essentially you are routing this game, if even for a short time, so nicks and such should be expected. While you are the only one that knows the magic number to make you feel better, to start the conversation I will say $1800 (just throwing it out, smarter folks will comment I am sure). Your set up and travel time, and a few hundred bucks a day to cover going from a new machine to not so new. I would also ensure you get paid if the machine is working or not. Just my two cents...
