I'm not an arborist, but in 25 years of owning hunting and fishing retail stores, I'd agree that it is the simplest way to create business. I'd sell guns to so many guys who would say, "... wow, you called me back...." So simple. Usually I wasn't the cheapest guy in the area, (that wasn't my goal), but the guys who were the cheapest were too busy doing low margin business to talk to someone who wasn't necessarily price shopping.
Like Woody Allen said, "90% of life is showing up."
I used to hunt ducks with a great old guy who beat cancer three times and was tough as nails. He owned a high performance engine shop and built drag boats. In his truck, we came up with the idea for a book on successful retail. It would be a hardcover book with one page that would list 3 things.
1. Return phone calls
2. Do what you said you'd do
3. Charge more for your stuff than you pay for it.
I think alot of businesses fail for one of these 3 simple things.
