Looking For A Dependable House Cleaner For Family Living In Washington

We have a very large 10k sq ft home. It includes a full finished basement with one bathroom, main level with master bedroom, two bathrooms, living room, kitchen, laundry room and den, and second floor that includes four bedrooms and bathrooms. I clean as often as I can, but being a full time working mom, it is difficult for me to keep up with it on my own. We have had a housekeeper for 10 years who had to resign due to preparing for her third child. I've been trying to keep up our home for the last 6 months and just really need some help. We are very flexible with when to schedule.
