An important part of my job is working with sub-contractors. They range from electricians, to plumbers to tree trimmers. Plus, don't forget the ever handy "jack of all trades." These last kind are the best to keep around!
I have found along the way you must realize the value of a good, honest, reliable sub-contractor. These are the people you can call at a moments notice and receive the best work possible and not be charged an arm and a leg. These are the people that make my job easy!
