Regular Sitter Needed For Our 2 Y/o While The Older Two Are At School

We are looking for a great childcare for our 3 children in Buffalo. It would primarily be for our 2 y/o who is active but still takes a 2 hour nap. It would include afterschool care for our older two for homework help, preparing a snack after school and working on crafts to keep the kids engaged. We would prefer a babysitter who has their own car, who does not smoke, who is CPR certified and who has college degree.
