Babysitter Needed for my Children

I need someone to sleep at my house from 8 p.m. - 6 a.m. in case my two children wake up and need something (I'm having surgery and won't be able to pick them up). They mostly sleep through the night, so ideally you would just be sleeping in the spare room and there in case they wake up and need a diaper or pull up change, etc. I do also have a small dog who is very friendly. This would be a great gig for a student who is willing to sacrifice a little sleep if the girls wake up, and have free rent for 2 months plus $500 a week.
