Thanks Sarabian.

I don't know if I will get a degree on computers in college because I'm still trying to think which career I'll be in. However, (sorry for asking too much) do you know like how old the apple products should be before I start taking them apart? Where can I get the stuff? I'm not so sure about ebay. How expensive should they be? For example, I've always been thinking abut taking apart the 2000-2004 iMacs and upgrading them or something; but thats too expensive. How can I trobuleshoot the problem that's going wrong with the iMac? Wait, I think I might have an idea. I take broken iMacs, try to fix them by getting parts from other iMacs and sell them, or not. Sorry for causing trouble, its just that I need to gain a solid foundation on starting a business like this. By the way, I'm already a geek and I'll never give up(taking stuff apart is fun) Lol.

Can you also give me some links that can help me with this problem(starting a repair business)
