Babysitter Needed

We are looking for a caregiver for our friendly, inquisitive 16-year-old son with developmental and cognitive disabilities for the month of July. We are looking for someone kind and empathetic, preferably with experience with kids with special needs or autism, who would like to walk with our son in the neighborhood or ride the T. We are looking for 2-3 hours in the mornings between 9-12 or 1/12-2 hours in the afternoons between 3-5 weekdays or possibly weekends. He has some language and is very expressive and communicative.
