you can make money off your hubs by using google adsense. First however I would suggest writing 5 or 10 hubs so you have some content. The sign up for a google adsense account at www.google.com/adsense
Basically people when people visit your hubs and click the ads on them you will receive money from google for every click. Obviously the better and more popular the hub the more traffic you will get leading to more clicks.
