OP, you are looking at paying $12-15/hr PER FAMILY. That only covers up to 40 hours, anything over that is overtime, time and a half ($18-22.75 per family per hour). You also will have to pay extra money for the nanny's taxes (I'm not sure how that works, I'm just a nanny and my employer uses an accountant, treats me as an employee, and gives me a W-2 every year, at their expense).
