Nanny Needed For 2 Children

We are looking for a great nanny to become a part of our family. We have had a nanny for the last 3 years but she is unfortunately moving. We have a 1-year-old boy and a 3-year-old girl. I work from home and have a very flexible schedule. Looking for help 2-3 days a week for most likely 10-15 hours. Weekends /evenings occasionally as well. Potential to do more hours if needed/ we can talk schedule as his naps change, etc . My daughter will be in school half the day so the primary focus is my son. I will pickup/ drop off from school. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets, who is CPR certified and who has college degree. Thanks!
