i also agree, I am in slightly different arena, but deliver the service, for the money you want to charge, sell the cleint the benefit VALUE FOR MONEY not cheap is best.
we have spent not a lot of money, but have a new van, clothing, all the right chemicals, commercially equipment, mops, vacuums etc, and the correct paperwork.
turn, smart on time, clean vehicle, and do the job, that client talking to other people is brilliant, and the word will spread, when leaving the client, offer to leave say three cards, something like "i'll leave a couple of cards and if you know anyone that needs the service get them to give me a call, thanks" sometimes they might even say my friend down the road is talking about having some work done.
how good is that a Hot referral.!!
good luck, the motto is work hard and achieve the results and earn the money. Set yourself a target and reach the target.
