Umm.. it wasn't about knocking on doors to get business.. We were in the middle of the "Asian ash beetle" infestation, which killed virtually every Ash tree in the area, and there were tons of them. There were more trees that needed to come down, than there were people to deal with them. We didn't even have to try to get rid of the wood, we'd just pile up the 16 inch rounds at the curb, and they'd be gone in a heartbeat. We'd get people walk up, and ask for quotes when they saw us work at a neighbour's property. Ash is also the only hardwood that will actually burn the day it's cut down. Sure .. It'll burn better in a year, but it's a hardwood that will burn fine today. The number of dead Ash trees completely screwed the firewood industry, at that time.
The scary thing about the Asian Ash beetle was that a tree could look fine, but it was the walking dead. The first clue was the suckers coming out of the trunk, as the body of the tree was stressed. Asian Ash beetles kill the tree by burrowing under the bark, which cuts the nutrients to the rest of the tree. The number of fine looking trees that were nothing but punk inside was incredible.
