I have a commercial cleaning business and I am going to start offering carpet cleaning. I need to know how much to charge for these cleanings. I have never done carpet so I'm not sure how to price it. I have four buildings that are 3000 sq. ft. and one building that is 10,000 sq. ft. Do I price by the job, by square feet, etc. Any help would be appreciated. I live in Ohio and it will be just two people doing it.
