$400 is $50/hr, hard to figure a good climber with own gear and insurance would work for less.
Depends on what one would think of as a good climber, which is hard to quantify.
If you were in some ridiculously expensive area, where cost of living is through the roof, or a ridiculous commute like to the Florida Keys for 2 hours each way, I can see $75.
Are they bringing big ropes, big LDs, big saws, risky trees with calmness and certainty, crane-work compatible, bang over trees 1,2,3? Maybe worth $600 if you don't
GL insurance is about the cheapest expense there is, next to bonding. That is what most CCs seem to carry. My GL costs about what One MS 661 costs.
Employees, trucks, chippers, shop space, sales, larger scale accounting, insurances, licenses, etc, etc, etc that are part of a full-service tree company avoided by CCs are the hard parts to manage, IMO.
In my area, contract climbing is not a serious option, and never sustainable for making even a modest living for yerself. You can ask anyone, and yer always gonna get the same answer. PNW??? ... a guy'd be a ton better off with a simple mom n pop treeservice. Ask anyone.
Logging?... ZERO contract climbers.
I'm surprised at this, regarding residential... Seattle or Snoqualimie?
