I'd look for after hours work in a parts store. If you have intelligence coupled with a pulse you should be a shoe-in for a job. It's a great ego boost because you will be smarter than 99% of the dolts who walk through the door. You will obtain funny stories to share here on the board. You will get an employee discount. Chicks will dig you because you can install their wiper blades.
I did that kind of work for around 15 years full time until I decided I needed to make actual money at my job. I did enjoy it though.
Freelance writing I wouldn't pursue unless you have a real love for the craft. It's very hard to sell stuff, and writing takes a lot more hours than you may think for a rather puny amount of income.
