That kind of gives me some hope, honestly. He's sorta adept at using computers; he can navigate the web fairly easily, though reading is a bit of trouble for him(it takes him 5x as long as a normal person), he's been doing fairly well with online typing tutor sites as well as basic math courses in Khan Academy. I'll have to look around and see what I can find.
I have worked with someone employed through a similar program during an internship at SAP.[1] Maybe there are opportunities available for your brother.
