Thanks for replying to my questions Chris. I'm relieved because I had thought I would have to write some code. However, yes, I have installed the OS(windows XP) for someone that had their computer's hard drive broken. I already have enough knowledge about PC's because I have taken apart some really old PC desktops(from 1996-2002).

However, in my area, I find it really hard to find extremely cheap PC's. (I know I sound like a complete noob). The problem with building PC's for me is that if I get a PC that has a slow processer and I upgrade the other parts (like RAM and hard drive) then it will be hard to sell it.

On the iPod thing, how can you troubleshoot a problem if I want to start fixing them. I also think that I'll get broken or old iPods and replace the broken iPod parts with the broken iPod parts. But I'm not so sure if the person that I'm selling my service to would be that satisfied with me doing that. I think that for now, I'll just examine the innards of some iPods, start selling iPods that I fix, and hopefully I'll be able to make some money.

By the way, how do you guys at iFixit get the parts? Do you guys still get it from broken stuff? Or do you guys buy it from the people that help make Apple parts for Apple.

You are right on the tour thing for iFixit. It would be pretty boring. iFixit is a really good role model for me as a business and consumer standpoint.

Again, thanks for the info Chris. Sorry for asking too many questions if I'm annoying you.
