Babysitter Needed For 2 Children

We are looking for a great babysitter for 2 children I have a 10year old girl and 12-year-old boy. We would prefer someone who could help out with light housekeeping and homework help. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. The hours would be 2-6:30 p.m. during the school year with occasional nights and weekends. More hours available during the summer months.
