Looking for a Saturday sitter (2x a month) 2pm (or could push to 4pm) till @10pm

Looking for help for our 14 yr old son on Saturdays (2x a month) from 2pm (or could push to 4pm) till @10pm …additional days/nights on occasion as well (if available) …single family home with 2 dogs. Our son is mildly autistic but fun to watch. Must feel comfortable to drive with him to get food (just through a drive-thru), going on walks, he loves to ride elevators so to the mall, going to stores to look at fans (Walmart, Home Goods, ect..) in the local area. Yes he loves fans!! Going to Dave N' Busters in Fair Oaks Mall...Really whatever he feels like doing outside the home... he’s very active and constantly on the move. Special Needs (Autism) and pre teen experience preferred. Summertime- Must feel comfortable with taking him swimming to our community pool. Pools are June-Sept. $20 per hour (firm). We live in Clifton VA off Union Mill Rd. Thank you
