Nanny Needed

We are looking for a great nanny for my 5-month-old baby boy in Issaquah. We are a family of 4. My elder daughter is in preschool and is 4 years old. I will be working from home for some part of the day and going in to work for a few hours everyday. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke, who is CPR certified and who has college degree.
