I made up some cards with my name and phone #, a note that says " I see you have some trees that need trimming. I will trade you the free trimming if I can keep the wood" you can get them printed on vista print for free. sometimes the people call back, sometimes they don;t. I just take new ways home from work everyfew days. if they don;t call no loss. it they do cool, you get some free wood.
