Nanny Needed For My Children - Full-time / Part-time

We are looking for a great babysitter for 3 children in Bellevue. We would prefer someone who could help out with light housekeeping (ie basic cleaning up after activites). We would prefer a babysitter who has their own car, who does not smoke and who is comfortable with pets. Looking for someone that can be present with my wife and 3 kids at the house while I have to work. Ability to transport to activities a huge bonus.
