Looking For Reoccurring Overnight Nanny

We are currently interviewing for a reliable and engaged overnight sitter for our two young daughters. We have a handful of trips each year that require someone to stay with the girls for multiple nights. We also have evening events each month that we need a sitter for that would not be overnight. Our ideal candidate would be someone who enjoys regulars sitting for a few hours but is also available and interested in staying overnight for 1-5 nights in our home a few times a year.
