Babysitter Needed for my Children

I’m looking for someone reliable and helpful to take care of my three kids for some days in September. My mom is out of town and typically watches them. My oldest daughter goes to school from 9-3:12 and my second daughter goes from 8 - 11:30 so this person will need to get them to and from school. My youngest son will need to be watched all day. Hours may vary but typically I’ll need from 8:45 - 5 p.m. most days.
