Quoted from DakotaMike:

As has been talked about many times, Tim is known to be VERY particular about how repairs and maintenance are to be done. Including lots of somewhat unique and “hackish” techniques and preventative fixes that he developed over his long years of routing. This combined with the fact that, last I heard, he has a policy of refusing to pay his techs, means that there is almost no one there at TPHOF to repair and maintain games other than Tim himself.
Tim admitted a couple of years ago that he needed to step back and be more open to help, and less strict about how things are done; however, it doesn’t seem like this has actually happened.
I agree with those suggesting he hire some help. Before saying that there isn’t any interested help to be found, it’s probably a good idea to actually advertise a position. If people don’t have the skills, then start them out as paid apprentice-techs, and build them up to full techs. Pay well enough and he wouldn’t have any trouble finding help. Hell, if I lived in Vegas and the price was right, I’d work there. I’m 36, am I young enough to be in this new “unskilled” generation?
