Babysitter - Full-time / Part-time

Honestly, it would just be overnight babysitting, while my husband and I go out. The kids will already be sleeping, I just need someone here, just in the case that they wake up or need something. Two out of the four are potty-trained; my oldest and youngest aren't. My oldest is non-verbal. It's not really much, just to watch over the kids while they sleep.
