Keep one thing in mind if you are banking on Google AdWords Revenue... Google is moving to a Pay Per Action Beta test model. That means you will not get paid on a per click basis but only if the visitor then moves to a particular action...
For example - Your visitor Clicks on the link, goes to the advertisers landing page... the advertisers goal is to have the visitor sign up for their newsletter. No payment is made (or received by you) unless the visitor actually does just that.
It`s a boon to advertisers, but could diminish the return on a site that uses google as income. Also - it unfortunatelly now makes your income based on the advertisers ability (or lack there of) to successfully set up a campaign to create the desired result.
