Housekeeper Job in San Francisco, California

I am looking for a reliable cleaner to professionally clean the inside and outside of most of the windows & glass door panels throughout a 4 story house. I have all the necessary cleaning products and rags. I am willing to pay $15/hour. I have not counted them all yet, but my estimate is that there are about 65-70 window. They are modern windows that tilt in so the inside and outside can be cleaned from inside the room (so no ladder needed outside to clean the outside of the window). This is initially a job to clean just the windows, but could lead to other necessary cleaning jobs at the house if a professional job is done on the windows.
