Babysitter Needed

We are looking for a loving and experienced nanny to care for our 6-month-old daughter. We have three older children (ages 5, 7 and 9) who will be at school, but may require some assistance once they are home in the afternoons. 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 comfortable with pets and who is CPR certified. Specific schedule is flexible but we are in need of 30-40 hours per week.
