I don't know what to do after high school

My son (18 year old, level 2) is graduating from SPED school this year. He can't go on to college like neurotypical kids do, and he can't work most entry level jobs with his disability status. Basically he will be a special "graduate" with no intended path. I can't just take care of him financially for the rest of my life either. We have until August to figure this all out. Does anyone have any advice? I live in England.
