Nanny Job in Vancouver, British Columbia

I am seeking a part time nanny for my 4 year old son with Autism Spectrum Disorder. My son Cruz was diagnosed 15 months ago and currently goes to Monarch House 4 mornings a week for behavior intervention therapy, and goes to a Speech Language Pathologist 1 day a week in the morning. At this time I am looking for someone who can nanny my child 4-5 afternoons a week. The time would be roughly from 12:30 - 6pm or . I would like that nanny to have a background in working with children with Autism, or has training in behavior intervention or SLP training. The nanny would be watching my son at our home while I am either working from my home office downtown or going to school a few blocks away. My son loves out door activities and exploring the sea wall, I am seeking someone who won't have a problem taking him to explore outside.
