I need to tell a short story through animation

I'm looking to pitch a story in around 30 seconds to a minute, and I want to tell basic outline of the story through animation. The story centres around boy who is slightly autistic, is bullied at school and against all odds, grows up to be a swimming champion. In order to get to the top, he does whatever it takes, even if it means hurting those that love him. There will be a voice over, over the top of the animation. In my mind the animation is drawn quite simply, and quirky, like the images I have attached, but I am open to any artistic interpretation.
