Nanny Needed For My Children - Now Hiring

I have 2. 5 year son who is developmentally delayed and was recently diagnosed with level 3 autism. He is a sweet, caring, but is full of energy. I am a single mother who just needs a helping hand with him. He is currently in daycare full time, but is attending elementary school for just half a day. I basically would just need help with him in the evening time. I need someone who is kind, patience, and has experience with working with kids, especially kids who are developmentally delayed. He loves to cars, building things, and out door activities.
