Babysitter Needed for my Children

Looking for a caregiver/companion for my son during my daughters event on July 25. My son is nonverbal and has autism. I need someone to stay with him and supervise him at all times from approximately 12 p.m. to 10 p.m. Duties would include playing games with him, helping keep him engaged, and ensuring his safety throughout the event. I will be present at the venue the entire time, but I will be busy hosting the event and unable to stay next to him continuously. Experience working with children with autism or special needs is preferred. Please message me with your experience, availability, and rate. Thank you!
