Babysitter - Full-time / Part-time

I am looking for Summer help with my three girls ages 7, 5 and 2. I am also pregnant with a fourth, due in November. I would be looking for 2-3 hours/day. I would mostly like you to entertain and play with the girls so I could get some house work done. I would want occasional help with household chores related to children. Which would be laundry, meal prep or dishes. We may also want occasional date night.
