I make a decent amount of money designing headers, banners & advertisements for websites. My main audience is probably affiliate marketers and blog owners, more than anything, I'm currently working with on a commercial SLR photography course DVD cover as well and all this brings on average about $400 a month.

I'd definitely love to look into affiliate marketing as there is money to be made there and i think it would be an interesting journey to build up a website to make money (even if its not much, even that would still be a success)
