Get Luke to the Junior Olympics in Houston

Hello, my name is Ryan Eames. I am a father of 3 boys. My wife and I are on a tight budget as she is a stay-at-home mom taking care of our 1-year-old. My oldest son, Luke, is high-functioning autistic and has been Speed Stacking since he was four. We recently took him to his first in-person competition in northern NJ. He had an absolute blast and in doing this competition qualified for the AAU Junior Olympic Games Sport Stacking Championships in Houston, TX. The competition is July 25-27. He has been talking about going non-stop since he found out he was eligible to go. We could use any help to get him there. Thank you in advance!
