Hello, hope no one minds if I butt in and add my two cents.

Timmy, I'm 15 and make 25-30 dollars an hour fixing computers, but I started by taking anything apart that I could get my hands on. Go to garage sales, thrift stores, goodwill, salvation army, etc. and pick up whatever looks interesting. Look for garages sales in the rich and moderately rich neighborhoods, I found a iMac G3 Snow a couple years ago for $20, complete with OSX 10.3 installed, and OS 9 OSX 10.1 and OSX 10.2 install discs at one of those. Go make friends at the local thrift store. I made friends with the person who tested all of the eletronics that came through there, and she gave me all of the broken (and sometimes not-so-broken, LOL) stuff that they got. As for a repair shop, start very small, and don't expand too fast. Unfortunately, there are nasty people out there who won't accept that the fact that their nice macbook pro is more broken when it came back to them then when it left as an accident, so you need good insurance before you get very big.

One last thing(and I can't stress this enough,) DON'T TOUCH ANYTHING THAT IS STILL UNDER WARRANTY!!!!!

Thanks for listening to my rambling, and have lots of fun!!!
