The adult version of my daughter Maria has handicaps, she's not blind though, she's deaf, but I imagine she's gotten into some of the programming on the station I'm pretty sure she could fix his apartment up so it would work well for him. As far as his hand goes, I might be able to talk to my husband or one of the other inventor types and see if they can't manage to get him a working prosthetic.
If you want to put him in an apartment as near or as far from you as you like, and just let me know where, and let him know to expect visitors.
