I hate to say it but 90 percent of the jobs that have been proposed are minimum wage range money. Do you really want to go to work driving pizzas or waiting tables for 40-50 bucks here and there but be treated like a high school dropout while you are doing it?

I would suggest something that can generate a little more cash, maybe even cross-train yourself in another skilled trade.
A real easy into job I would suggest is mowing lawns. It will keep you in great shape and make 20ish per hour average.

The people who mentioned things like website development or other IT jobs hit it right on the head too.

A few years back, the mechanic I used to use was a Continental Express pilot. He and his buddies had a car shop together and all worked flexible shifts.

I am a corporate pilot and my lifestyle is a little different but still much the same. Here is what I do on the side:

Sell cool things I find on Craigslist/Goodwill
Sell car parts for a friend at commission
Flight Instruct
Contract fly
Manage a GPS tracking software for the company I fly for(negotiated into my salary).


Point being, is I never stop. Lots of work is out there, knowing the right people definitely helps too. Good luck!
