Nanny Needed For 1 High Energy, Smart Child

I am looking for a nanny to work with my 5-year-old ADHD son five days a week. He is high energy, so someone who loves being outdoors; taking walks, playing games, etc. He does better at school when he has this time to play hard the night before, hence looking for someone who can come Sundays. I am about to have a baby, otherwise, it would be me doing all this activity with him! He is so smart but really needs the attention on him so he can get his energy out. He loves exploring, talking to people, getting challenged, and getting dirty outdoors. He also occasionally enjoys board games and reading books, but is not so interested in art. I am looking for someone reliable, strong in communication, and who isn't afraid to run around with him, but will ensure his safety, since he does enjoy pushing limits.
