Nanny Needed For My Children

I’m looking for help with my two kids, 10-year-old son and 8-year-old daughter, while I’m at work starting July 15. I only need help Wednesdays but I do need someone all day into the evening. This would extend throughout the summer. I’m mostly concerned with finding someone my children can be comfortable with while I know they’re safe. We can discuss specific responsibilities when we meet.
