Nanny Needed

My child is 11 years old and is nonverbal and has level 3 autism. I am looking for care on random days here and there, and would not have a set schedule. During the week if needed would be around 2:30-unknown and weekends would be random so not sure I'm on exact times as well. He loves to play outside, ride on our golf cart, or play inside. I would love someone who has a background with taking care of someone with special needs who understands well and is patient! New to looking for a sitter as we usually use sitters in the family, but need someone if all family is not available, so pay is flexible as well- please send a message for all questions about what we are looking for! Thank you!!
