I need an actor

I am looking to hire an actor for about 45 mins. to an hour for a b- day party for 6-7 year olds.
It’s a Ninja Kidz theme (the you tube channel).
The actor will play a real ninja (I will supply the t- shirt and head band).
The ninja will show the kids a few cool moves about 4 -5. (Easy found on YouTube) and possibly assist an obstacle course (very easy- home made).
If you know anyone who would be good around kids and can play the part?
I am really looking for a male actor please..
