Doc band

I’m asking anyone who can please help,  my son is in need of a Doc band. Which is basically a helmet to help him reshape his head. If he doesn’t get it then later on in life he will have trouble with his jaw, his teeth will come in shifted, if he ever wants to play in any sports he will need a custom helmet to fit.  Also the back of his skull to hold his brain is higher then it should be. So please any donations will be more than great full.
