Great place to write for - Freelance Writer bei Wikinut: Mitarbeiterbewertung

You can write articles you want to write. Pay is based on readership. However the site gets a lot of hits. So you can write a lot and earn a lot. Payment is sent to your PayPal account. Which for me is great. I have a debt card with them and a savings account with their bank affiliate. I find saving much easier that way. Good way to practice what you are studying.
