To have a crew of two men come to your house and trim your trees will cost roughly $150 per hour, less rural areas, more near the big cities.
A typical tree can be pruned out and the mess cleaned up in about an hour, less for a small tree, more for a large wide tree.
If you are asking how much the climber gets paid, typically they make $40,000 to $80,000 a year, so you can do the math.
