Babysitter

Im looking for someone who can be at home with my kids from 3-7:30ish four days a week and all day on Saturdays. I work until 6 or 7 five days a week. Both of my kids love home and are yet to get involved in afterschool activities. Taking them to a park for a bit or just hanging at home until I get home is fine. Light cooking is much appreciated as I dont want them to eat too late eat day/night.
