Babysitter

We are looking for a great nanny for 1 child in La plata. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. My schedule changes weekly but I would need someone to pick my son up from school on some evenings at 4:30 and stay with him until 8 p.m. that could extend to 9:30 p.m. on some evenings. I need someone on a few weekend days as well that can be available as early as 7:45 until 8 p.m. or 9:30 p.m.
