Nanny Needed

Have 2 girls and 1 boy that take the bus home. The bus stop is 1/2 a mile from our house they all three walk home. The bus drops them off at roughly 2:45 p.m. The boy is 11 and self sufficient the girls are 5 and 7. Would like if someone could either walk or drive them back from the bus stop. Then help them with their after school routine. Also, if possible start and/or prepare dinners. There is also a 15-year-old boy that gets home from school around 4 p.m. And a 12-year-old boy that gets home from school around 5. They are self sufficient and help with their after girls and chores. Mom should arrive home around 5-5:30 p.m.
