I'm growing my sound-and-lights company and have an opportunity to install a small system into a local venue that's opening soon. I'm trying to determine how much to charge them for the system. My initial thoughts are to figure this out based on 2 factors: how much the rental is, and how much i need to be paid for my work. I know my hourly rate , but what do I charge for the actual lease of my sound system? Here's the gear going in: (2) 2 x 15" mains (2) 1 x 18" subs (4) 1 x 12" monitors (2) xti4000 amps (2) xls2500 amps $2000 worth of mics $1000 worth of cables and stands typically i hire out this system (with myself setting it up and running it) for $250-ish per night. for an install i dont need to setup nor tear down. so i should charge less than $250 per night, right? i mean - 90% of the work is lugging the stuff around, set up, ring it out, etc etc. the only real fun part is mixing, and with an install that'd be a much larger part of the job. insurance will run $500 per year tops, and probably much less than that. a typical gig at this place will be 4 hours of music, with possible set change during one of the breaks thoughts?????
