Jeff, what area are you in? as for pricing,it comes down to confidence, there are people who will pay for a top line service, and you should direct your marketing to-wards that end of the market, why would you want to do 6/7 cleans to achieve the price you can get from doing 1 decent job, its not about volume,its about profit,maximum reward for minimum effort.
Just my thoughts, and not a attack at any one.
