Babysitter Needed

I'm looking for a great babysitter for 3 children, 13, 11, 8. Afterschool pick up and until 7. It is flexible on days but minimum 3 days in a row. I would like someone that will help with homework and chores as well as making dinner for the kids. There could also be some transporting of kids to activities. Some light tidying up of messes kids make would be part of our caregiver's responsibilities. We do have a dog, so please consider that when applying.
