Ron,
I am tinkering with starting another business next year, something franchisable, etc. I know this----if i were starting something else I would put the name in a phone number. examples:
1-800-PRO-WASH
1-800-GOT-DIRT??
1-800-Wash-man
1-800-wash-guy (sound familiar???)
One difference may be that this would work best for a service business doing heavy advertising to many people and wanting many calls to come in. I imagine your business would be more of the type where you hunt down a small group of people to advertise to (property managers, etc.). Since I believe that is the case, you may do just as well with something simpler. Another advantage to the 800 number is that all the calls from around the country would come to the same place, and your crew could dispatch out the work.
