Best Place to Post for Nanny Wanted Ads?

We're a young couple expecting our first born in November. My wife will be taking her maternity leave but we're hoping for a part time nanny a few hours a week to help give her a break and potentially help with small chores around the house. I would love to post this to a college job board as that's what I used when I was in school to find work but I can't seem to find any similar job boards these days. Care (dot com) seems to mostly have higher priced professionals but we would be happy with a local student.

Any thoughts for a good place to reach out?
