Babysitter - Full-time / Part-time

My son has to be at school Monday through Friday by 830 a.m. He then gets out of school at 330 p.m. Typically, he's up and dressed by 750 a.m. We just need someone who can pick him up in the morning, drop him at school. and then pick him up from school nd dropped back at home. His grandma is at the house all times. He is 6 years old and autistic so extra care is required as we are working on emotions and how to express them.
