You want to make a quick buck? Hammer out some freelance jobs on odesk.com, freelancer.com, etc. You can spend a week's worth of evenings plus the weekend and net a good few hundred dollars. The advice I just gave, while accurate, isn't very valuable because it doesn't scale. I've done it a few times, bought myself a nice holiday last year with the proceeds. But it's not something that grows, you have to keep grinding away to create a recurring income. I preferred it when my websites regularly produced £60/month in adsense revenues without me having to lift a finger. (That not-lifting-finger part only lasted about a year though. Now I barely make £6/month because I've neglected my sites).
