Building Revenue

As you know my main site is at Dominique's Desk I'm been thinking of how best to build up revenue through  google AdSense. I've been reading about how people are able to cash out $100 a month and it seem like it's so easy to earn from a  CPM network. I'm earning a rather dismissal amount and it's taking like forever to reach the $100 before I can cash out.
I would certainly prefer a more regular income and even get some long term sponsors but am still loss at how to seek them out. I guess for now I'll be sticking to Adsense till something better turns up.
