I am obviously in Canada and so my rates will be different. When I started my business I contacted local business. I told them right off the bat what I was doing. Most guys here are working almost exclusively in the oil and gas industry. Rates seemed to vary hugely. I picked a price in the middle. After the first year, I increased my prices by about 20%, some to help with the extra cost of fuel and insurance, but also because I noticed my rate wasn't working. I am presently charging as follows: T770 - $120/hr, Tandem gravel truck - $110, Delivery - $100, Labour - $35, T770 with mulcher - $150-170 (depending on customers requirements) (Teeth extra if rocky soil). I haven't gotten any complaints about my rates. The mulcher definitely uses way more fuel.
Some local guys are cheaper per hour for their machines, but charge for attachments (on site: used or not), trailers on site, vehicles on site, operator extra charge......... Had one guy start a new business up last spring and he was offering his brand new CTL Kubota at $60/hour. Others in the area are $125 for there MTL. There is a huge variety in prices. I have found that if I offer a good service at a reasonable rate, customers do most of my advertising and no one has complained about me raising my rates.
Best of luck with starting up. First couple of years are really a challenge.
