2hr childcare needed, please help!!! - Full-time / Part-time

Hi, I have 4 children. 3 children in home, one 14, one 4, & 3 all girls inside the home. I have a son that is located outside the home that is 10 years old. My 14 year old is in high school. She gets out at 2:45p she rides the bus home and will make it home by 3:10p she will stay with our 3 and 4 year old until we return. Hi, I need a sitter for our younger kids from 1:30p-3:30p until our higher school kid comes home to be with them.
