Maid wanted

We're in the market for a house cleaner. I realize that the title is slightly misguiding, as a maid is usually someone who comes often or maybe even lives with you. While I would LOVE one, it's just not in the cards. I can however, have someone come clean my house a few times. So, does anyone know of a reasonably priced, reliable, and trustworthy house cleaner? Say in the range on $20 an hour or less. I'm hoping to have someone come scrub our home a few days before the baby comes, and then again two weeks later. The last thing I really want to worry about is scrubbing my floors and mirrors just before and after having a baby.
