Babysitter Needed For 2 Children In Brooklyn.

Im looking for a babysitter for my two children, ages nine and six, in Brooklyn. The job would be between two and five afternoons a week, though precise hours and number days are flexible based on your availability. It would involve picking them up from school, bringing them to activities and occasional play dates, and encouraging them to complete homework, clean up, etc, as well as, ideally, reading with/to them, drawing with them, bringing them to the park, and things like that. We have a dog and live on a second floor walk up, and would prefer a non smoker.
