Nanny Needed

We are looking for a great babysitter for 3 children in Saint Petersburg. We would prefer a babysitter who has their own car and who does not smoke. We are looking for someone who is able to pick up the kids from school (5 mins from our house) and watch them until we get home from work by 5 p.m. Applicant would need a vehicle that can hold 3 booster seats. Pickup is at 3:30, so an hour to 1. 5 hours of light household work prior to pickup would be preferred. There should not be a need to stay past 5 p.m. if that is an issue.
