Babysitter Needed

Seeking a babysitter who can hang out with my 12-year-old son a few afternoons each month while I work from home (onsite). He is autistic but verbal, though can sometimes be difficult to understand until you get to know him. Sitter would play games, accompany him to the community pool, go outside while he draws with chalk, maybe go to the local park together, otherwise just chill with him at the house while I work.
