Sitter in Muncie, Indiana

I'm a 15 year old high school student on an early college track, I am looking for part time babysitting in the local Muncie, IN area. I have been looking after family and children at my church for some time now and would like to offer my services for a reasonable fee. I can sit for all ages, ranging from 6 months up. I do prefer that if I am sitting for an infant, that it be my only charge. I can handle up to 3 children at a given time as long as they have a range of ages, triplets may not be something I am comfortable with.
