Ask HN: How do I earn money as a teenage programmer?

I'm having trouble working this out, because I have to earn money to pay for car insurance and such, but software companies are not willing to hire people my age for good reason. My resume is also limited because I have only built applications for a few businesses who I had previous connections with. I'm looking for advice for how to start freelancing, because that seems to be the most viable way, without a large resume to start.
