Babysitter Needed for my Children - Full-time / Part-time

We have a 5-year-old starting kindergarten at the end of August. We are looking for someone to stay with her at our home from 3:30-4:30 Monday-Friday (and 1:30-4:30 on Wednesdays (someone will pick her up from school and being her to our house) and then, at 4:30, take the5-year-old in our car to pick up our3-year-old at a nearby daycare, bring them both back to our home, and be done (well be done with work by then). Thanks!
