If the economy is hard, everybody with a chainsaw and a pickup is out there working the market. The only way to cut down on the hack supply is to have a good economy and a tight market for tree work...then the hacks find something else to do. Otherwise, get used to 'em.
I had a guy come into my office today, trying to get me to drop all my business and go cut down a 60 silver maple. It was out of reach for his 30' ladder, and he HAD to get it done today. After explaining that I didn't have time to do it, I referred him to another climber who eventually came out and did the job in 40 minutes for $150 (I told him what to charge).
Somewhat over two houses and some utility lines, they never used a rope to lower anything. The guy came back by my office later to get the rented MS170 sharpened, since it was his only saw. $45 rental, $10 saw sharpening, $150 climber rental, and $450 revenue from cutting down the tree.
Hack was a happy camper.
Oh! Just one thing...I never got my $10, and the climber hasn't seen his $150 yet, either. We'll see how that turns out.
