I can still trim mine, so I do not have first hand experience hiring someone, but I have seen warnings about hiring the guys that drive around and offer to trim these. Also, make sure that who ever you decide to go with takes the trimmings with them when they leave. If I recall correctly others have reported problems when the contractor left the cuttings and the trash company balked at picking these up as the homeowner had not done the work. (this was the impression I got from another thread).
