The Maids and Merry Maids are paid poorly, and if possible, maybe you could hire an individual recommended by your neighbors? I strongly recommend the chapter on The Merry Maids in Barbara Ehrenreich's book, "Nickeled and Dimed: On (Not) Getting By in America". It's an eye-opener.
I have a woman who comes in to clean, who works for herself and has an assistant, so please know I am not against hiring someone to help me out. She does a very good job. I give her a tip at Christmas time, usually a week's fee.
No matter how you slice the baloney, there are always two sides!
