Hi there. And welcome from fellow newbie
Well I have had the most succes promoting webcams. And my all time best sponsor is
Cams.com. It's a very easy sponsor to convert. Make some galleries with webcam models and some direct lnks to cams and your on your way.. Also it's easy to get hits with a webcam site... I have about 300 uniques a day on my danish website, and I make about 600$-800$ a month on webcams... So if you could get 1k your should be able to make at least twice that.. Depending on what kind of traffic you get.
Good luck..
