I have decided to charge .22 per sq. foot to clean office space. I am a bit confused as to what to charge if the cleaning frequency is 2,3,4,5 times per week. Do I charge $15 less than the once a month fee for cleaning more than once a week? I need examples of once a month fees/ 2,3,4,5 x per week fee/ bi weekly fee/ one time only fee/ and (total monthly fee) if more than once per week cleaning. It's hard finding specific information to help. Thank you
