Babysitter For 5 Years Old Boy (autism) But Very Social

I am looking for a babysitter for weekends, but mostly Saturdays, Sundays on and off (hours can be either set or adjusted weekend to weekend). We are very flexible. Person with reliable vehicle is preferred to take him to playgrounds and walks, keep him safe, engage in playtime, help with feeding, change pull-ups (he is currently potty training). He is very loving and extremely social but struggles with speech and fine motor skills. He does not have a typical autism but falls under the spectrum.
