Time study: take an area and or a special project and determine how long it will take to do everything in the space, then take another area, etc Until you do the total space. This will give you an idea of approximately how long it will take to clean those areas properly.
After you finish this for the whole job you will have your labor hours. Take those hours, and your total costs (taxes, supplies, equipment, overhead, admin, profit, etc) and you have the total price for a one time cleaning, Divide the total sq ft by that figure to arrive at you sq ft price.
You can test this by starting at a fair price per sq ft times the total sq ft. Then increase or decrease that price per sq ft to compare with the previous price you arrived at from the hour concept.
Then do as I mentioned above to arrive at a monthly price.
