I hope my price didn't offend anyone, that's a realistic price for up here in Taxachusetts. $1000 for 10 hours of work using a $20,000 tool is not out of the ball park in my eyes. $300 cash is better than nothing. One major thing to think about is liability. Here in MA, if your a contractor of any type you need to be licensed, hold a OSHA 10 card, and be insured with both liability and workmans comp. Most if not all contractors here won't let you step on site unless you have WC insurance. Liability insurance is a must have today to protect you and everything you own from being sued. It's a sad thing but it is reality. I'm sure others will chime in or call me crazy but these insurances are not cheap by any means. So now if you factor in how much insurance costs, $100 an hour is very reasonable. If it was me, I wouldn't do any side work unless I had insurance and a contract signed by the property owners and general contractor if there is one (easily drafted by a lawyer for a few hundred bucks). A contract will state who and what you are responsible for, and also any clauses. For example in the excavation business they usually have a rock clause written in their contract. If you bid the job for a $1000 and hit rock while digging, your labor could easily triple. There goes any profit, and could easily wreck your machine. I've had rock blasted many times with TNT and have seen equipment damaged. Homeowners would love to hear that you are insured to protect them. What if their kid fell in your ditch and hit their head? What if a neighborhood kid fell in your ditch at night and got hurt? What if you drove the tractor through the side of their house? Too many ways for something bad to happen, and sadly it happens every day. Just my 2 cents....
