Looking for babysitting jobs in CM24 or CM23

I'm Faith - a 17 year old looking for experience and a part-time job in babysitting. I am an older sister of an 21 month old, and an older cousin of a 9 and 7 year old, with some experience with supervising them and helping out with whatever is necessary, as this is something I very much enjoy. I am available any time, which may change from September onwards when school starts again. I live in Stansted (CM24) and while I have a driver's license, I currently cannot drive - however, I do use public transport quite often.
