When I used to take commissions, I was often asked for a price quote. So I asked the prospective client how much he made an hour at his job. He often hesitated to tell me, obviously sensing a trap. Then I asked him if he thought having a half million tied up in tools and inventory, fifty years of building experience and skills, and a reputation for quality work and an overwhelming personality, wasn't worth at least the same amount? I sometimes added, "did you come to me for the best, or for the cheapest you could get?"
Another great old friend who no longer submits here but was instrumental in getting me to subscribe to the ALR, Cody Tetachuck, once told me he used to tell a prospective client, "You can have it fast, cheap, or good. Pick two." You can have it fast and cheap, but it won't be good...you get the idea.
