Naturally you don't have to just stick to yard mowing, washing cars, etc. These types of jobs are something that does not require too much skill/training to do an adequate job, but you can do jobs using any marketable skill that you have.
Just don't take on something that is over your head, costing the customer more money due to damaging something, or bad reputation will cost you way more lost money in the long run then turning down the job.
I have had quite a few jobs fixing what the clients "guy that knows computers" did.
Anything you would recommend for a 13 year old who's technically inclined? Just want to do something for the experience of it and not really mainly for the money.
To gain experience just offer to check on broken things when friends/family bring it up, or there might be a local charity that needs donated electronics fixed. No one is going to take a 13 year old seriously to pay to repair their stuff, especially not pay you to figure out how to fix it. I don't mean to be rude or anything it is just the reality of the mater, I think is good that you have the desire to learn, way too many people these days that don't know how to fix anything for themselves.
I tinkered with a lot of things when I was your age and learned how to fix it or build it (and broke a few things worse then when I started).
