Lot of house call services (like heating/airconditiong) use $60 per hour for straight service calls (in my area). That's $60 if they're there for 15 minutes or 1 hr. Materials are extra.
Like Ron mentioned: depending on what your business set up is, what you are cleaning, how many people you employ, do you have to reclaim, etc., etc., etc. will determine YOUR portion of the cost then profit is added on to it. What the market will bear in your area for each specific type of cleaning will vary widely.
Cleaning CAN range $45 - $150/hr plus.
