Look in the phone book for larger snow removal contractors in your area and give them a call. Also go to the SIMA web site and look for contractors in your area, that should be available on the fre side of the site. http://www.sima.org
When I started five years ago going rate was $ 35/hr, just looked at a truck a guy was selling, turns out he did alot of sub work (3 trucks worth), was geting 30 - 35/ hr, he didn't get specific, but did say he often times didn't get paid from contractor or not all, I don't know what he had for insurance, ect. I have seen rates advertised in the newspaper for $ 50/hr, I looked into what I could pay subs this year it was definitly in that range, these are for pickups with straight blades, more experienced more money obviously.
