I'd atleast try to help your old man. I mean, unless he was a shitty abusive father, I think you atleast owe it to him to try to help him out.
Also, yea, do what swissguy says. Make him install wordpress or something.
Say, here is cpanel, you need to install it. Have any questions? Use google and youtube.
Thats a great way to measure if they'll actually have a chance. I know when I started on my first site, I knew piss all, like absolute shit. It took me like 3 hours to install wordpress. I had no idea I could install a script in like five seconds using fantastico or softaculous. With hardcore googling and youtubin, with occassional pornhubin I figured my shit out.
