Freelancing outside the US/EU

Dear HN, I'm a college student and also have a full time job during the day so I can pay my tuition, rent, et al. I've been wondering where should I put my efforts so I'd be able to live with more comfort.

For the past 3 years I've been working with application support, but my goal is to work full time with development, but I just can't afford taking a junior position somewhere else because I'd run out of money. So I ask: any suggestions on where specifically I should put my efforts to find my way on online freelancing? I've signed up for some of the sites suggested here, but I'm still looking for the area that demands the most. With USD1000 a month I already could pay the bills, anything else would be extra.

I've already invested some time on two certifications (SCJP and ITIL) but since I have no enterprise experience they would still take me as a Junior -- anyways, I passed both.

I'm willing to spend any free time studying something new, just wondering what would be it.

Thanks in advance. PS: I'm in Brazil.
