Nanny Needed For My Children

I am looking for after school help with my elementary school aged kids. My son is 8 and my daughter is 6. Ideally looking for someone to pick them up from school at 2:35 and help with homework/reading, chores, and snack time until 4:30. This would be 3-4 days per week. Kids are well behaved, no behaviors or disabilities. We live in the walking zone so they cannot ride the bus, but you can walk to/from my house to their school.
