Exmarkboy...I think you need to lighten up a little. Clear Difference brought up some valid points and wasn't being a jerk about it or anything. Personally I would never hire a minor to run power equipment on my property...EVER. And I don't know how things are where you are but where I am you need an arborist license to trim trees and I'd be surprised if there wasn't such a requirement where you are too.
Keep in mind that you're on a professional forum here and it's not your personal blog...people are free to post on your threads and comment as they wish. Chances are that you're breaking several laws in doing what you're doing and exposing those who hire you to significant personal liability.
