I found a good article the other day and shared it with my coursemates. It was appreciated by them, maybe it can help you too

As for any make-money-fast schemes, you'll struggle. That's why we're encouraged during our 3-year course to ALWAYS be adding to our portfolio :/ It's not something you can do over night, it takes a fair amount of time to get a solid portfolio up that'll earn you the jobs you want.
Saying that, if you're really that desperate to make money and you're relatively confident in your abiltiies, why not give this site a look at?

Again, you may need to show some previous work (portfolio, portfolio, portfolio!) in order to be taken seriously but if you want it that bad this could be a good place to start.
Good luck mate and hope your situation improves soon!
