Driver / companion needed for middle-school son with special needs

Seeking a responsible babysitter to support our 6th grader, who has developmental disabilities. Responsibilities include: school pick-up (3:10pm), driving to after-school activities, and bringing home afterward (~5:30pm). Additional hours available for helping him with basic tasks after activities (unpacking bag, choosing clothes for the next day, etc.). He is a joyful and active boy with a great sense of humor. We have a vehicle available for use. Ideally, we would love help for him five days per week, but we're happy to have someone 2-3 days if that's what your schedule allows. We also have a need, T-Th, for someone to pick up our 4-yo child at 2:45pm, which could be added to this role.
