I can tell you what we would charge for a house such as you described in SLC, UT. We base our estimates on an assumed 20-30 a man-hour, depending on the difficulty of the job (also difficulty of the client - I am a believer in the "bitch tax"...). A 1500-2000 sq ft house would usually run about $80 a cleaning, assuming biweekly. a little more if it is monthly. I think our pricing is fairly typical for independent cleaners in our area. It sounds like the average must be higher where you are; I plan on a house that size taking one good cleaner 2.5-4 hours, depending on the house. $50 a manhour would make the price between 100 and 200, which would never fly here!
