Babysitter Needed - Full-time / Part-time

We are looking for a great nanny for 2 children in Midlothian. This would be two days a week during the school year starting in August 17th to June 4 as I am a school teacher . We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. Our oldest son will be coming home from school around 2:30 so he will only be there for the last 30 minutes of the day.
