Occasional sitter for date night only have to watch kids over baby monitor

We are looking for a reliable babysitter for my husband and I to have date nights here and there I have a nine month old and an almost 3 year-old you would only be watching the kids as they’re sleeping over the baby monitor and we would be out a few hours max. The kids never wake up in the middle of the night, so you would only be there to watch them and to ensure they’re safe.
