Other ways to earn money...

Like others have suggested there are article writing sites, surveys etc. Then there is Mechanical Turk which pays for tasks but only in Amazon credits if you aren't in the US or India,auction sites or Amazon. Plus there is a site that I had forgotten about for a bit called Slice the Pie which pays for listening to songs and rating them. I've been aid three or four times. If you have one star,which all members start out with, then you'll earn 10 cents per song. A dollar a day even if you only listen and rate ten of them.

You can try article writing sites, micro job sites, blogging, survey sites etc. For article writing you can try bukisa, triond, squidoo, hubpages etc. for micro jobs you can try microworkers, minute workers, mturk etc. For survey site my favorite is Global test market.
