You can try BST for a start to see job opening. Other than that, you could just concentrate on building your own blog (and if it's famous someday, you may sell it ) Payperpost (and other similar site) can help but I heard some story about Google penalising blog with PPP, so I must say, try it at your own risk.
To promote your blog, you can try xomba. Post some original articles related to your niche there and include a link back to your blog. The good thing is that they even split Adsense revenue with you 50/50 on everything that you post.
Another thing you can do also is comment on other blogs. This gets you precious backlinks, and it gets you seen on blogs that have thousands of daily readers. Check out the likes of John Chow and Shoemoney. They are 2 of the best who make a living from blogging. There are more...many, many of our own DPers have blogs as well. I'm sure you can find them hanging out in the Blogging forum under Design and Development>Content Management.
