Sitter Job in Saskatoon, Saskatchewan

I am looking for a part time sitter for occasional Monday and Thursday nights from 6:30-9:45 while I go to my night class. The class runs until mid march. I have someone that comes in every second week and another friend that can usually help me out every other week but sometimes works late so those are the nights I would need someone. I have a very well behaved, independent 4 yr old son. He would be fed before I left, and is in bed by 8:30. I would need you to come to my home and have your own transportation. I am a single parent / student and given the very little amount of work required can therefore only afford to pay $20 per night.
