Moving to Uk

Hello.I am trying to bring my friend to Uk. He is 20 years old, diagnossed with autism and currently living on its own in Netherlands. He can hardly survive, with no family support. His family abandoned him due to his dissabilty, he is facing the world by himself for the last 4 years. I am trying to find a way i can help him.. Could you please advice me if there is any possible way I could help him? Really appreciate..
