Afternoon Sitter Needed For Twin 5-year Olds! Potential For Full-time This Summer

We are looking for a reliable sitter for our twin 5-year-old girls starting November 11. They are in AM kindergarten, so looking for someone Mondays, Tuesdays, and Thursdays 12-5. Ideally, someone with some flexibility for days they have off from school, but not a requirement. Also potential for this to turn into a full time position over the summer! We would prefer a nanny who has their own car, who does not smoke and who is comfortable with pets.
