Seriously. I think the more important thing is that 10-15 off in this price range (lets say under 80). When I was young I would do this to get the job. Anything to get the job and could not fathom the idea of losing the customer over 10-15 or the words "I need other estimates and will call you" This often led to me doing the yard, but was super unhappy and pissed each time I did the yard because that 10-15 made a difference to me. You are a solo guy and part of the beauty is you can pick over your customers.
