Childcare Needed

We need a babysitter for our older girl for one night. We would also like to have someone we can ask to babysit for occasional date nights. This may be for just the older girl who is 12 or both the older and younger girl who is 8. We are also looking for someone who can occasionally help pick up the youngest one from school and watch her for a few hours. Our kids are pretty chill so weekends would just be hanging out with them, no homework or housework. Homework help would only be needed when the youngest one is picked up from school. We do have two cats and in-home surveillance.
