Computer repair job for 15 year old?

I'm fifteen and looking for an online job that has to do with computer repair and help. I am very efficient with Intel hardware and Windows software. I currently work as a foods employee at a semi-local amusement park and have been for 2 years (about an hour drive away.. two hour bus ride). I am not sure where to look for employment. Looking for a better way to earn money for a car. Please suggest some places that hire for computer repair and servicing. I spent last years earnings on a custom build... spent about $1500 on my desktop and had a 22" hdtv i hooked it up to.
