I agree, consistency is the key. People get a taste of your work, if it's consistent in quality, people will then promote your business for you. I think I had said earlier in the piece, that I hardly advertised my business, I was getting calls through other customers I had previously cleaned for. Thats how a business grows. One can spend thousands of dollars and a lot of time promoting ones business, but if the quality isn't there, you've just wasted your money. There are a lot of people out there that do not produce what they advertise, and then they scratch their head and wonder why their business isn't booming.
As the saying goes and will last, Honesty is the best Policy. Keep your business above reproach and watch it grow, you'll be amazed.
