Being in the commercial cleaning industry, there are so many times that I get a call from a potiential client. They would ask if I can give them and estimate of how much will their specific cleaning task cost? 

There are so many variables that determine the final compensation. Like square footage of the facility, frequency of cleaning, their client traffic, number of employees, even the number of restrooms in the facility. So I never give estimates over the phone. And let them know that what they're really looking for is an exact quote, which they can obtain after I perform a walk thru of their building or office space.
