Jennifer, offer babysitting - EN4 Hadley wood

I am in need of an occasional babysitter for a 10-year old boy in Hadley Wood on weekend nights once in a while. I am in especial need of someone who can work December 10th from 6pm until late (1am or so), but would also like this minder to look after him on an occasion beforehand so that he is comfortable and familiar with the minder. There would then be occasional work from time to time but well paid (15 pounds per hour). Need someone friendly and able to play games and have fun with my child.
