I'm cleaning a dentist office one per week there are 6 offices 15x15, one 10x10, one waiting area and front desk 20x20, one small lab 15x5, 2 small bathrooms, one kitchen 15x20 half of the office is carpet, and the other half is hardwood floor. I'm getting 250.00 per moth. I know that I'm getting the short stick of the dial, I just want to know for how much?
