Nanny Needed

We are looking for after school help with our 3 children (soon to be 13, 10, and 7) - ideal for a Northwrstern / colleges student. Responsibilities would include (but not be limited to): after school pick up, drive kids to sports practice, supervise homework, keep kids on schedule, heat up dinner, light kitchen clean-up after dinner. Days and hours would be regular (ideally 3 days between Monday and Thursday, roughly 3:30 to 6 / 6:30), but we could be flexible on the exact schedule.
