Babysitter required in St Peters

I need a babysitter for a few hours this evening in St Peters. Can be for after bed-time, I have just moved to the area and this could become a permanent casual thing. I have two boys, youngest is age 1 and older is aged 4. They share a room. Both lively and spirited boys, generally go to bed at about 7-7:30 after dinner and bed-time. Older one can be a little bit wild just before bed and the younger one takes a little bit of time to feel comfortable but they generally go down by 7:30-8:00PM.
