20' Tall 10-15' wide I need to raise the base of the foliage about 4-7 ft. each tree & one needs to be cut down. I figure about 20-30 minutes per tree from pruning to clean up. 3 Man crew, 1 guy on the Power pruner & 2 guys hauling brush/debris. Are my figures right? What should I charge? Thanx and sorry for the constant questions guys. I'm making the transition from lawn care to landscaping & tree trimming.
