A very good idea

If you have got shoulders like Arnies' and the tree you want to trim back has branches that grow out from the trunk roughly at right angles. I don't qualify on both counts ! My tree is a Rowan which grows straight up, and trying to control a chain saw that weighs about 10 lbs on the end of a 12 foot pole, is no easy task. When the branches are OK it cuts through them like butter, and I am working off a ladder, also not to be recommended. So the tree lives to fight another day, but I will give my friend a call,( When Telecom deigns to re-connect us!)and he is a Pro' and will soon do the business.
