I haven't found much info on a kids size suit. The only orange jumpsuit I've found is a nasa flight suit that runs around $60. Everything I've looked at on amazon is for younger children. He's 10. I saw a few mentions of using a pattern. That's a possible option if I have to go that route. The final option is buying the Rubie's costume and modifying it. I'm not sure of the quality of the suit itself or the accessories, though. Hopefully someone has some ideas to push me in the right direction.
