Since you did not get in your first time, would you like to try Commission Junction?

It is basically a site, where you can pick and choose what you want to advertise. Once you sign up, you can apply to any advertiser you want to advertise, and if they accept you, you can place their ads on your site. Plus, once you get a large enough pool of advertisers (after getting their permission for you to use their ads), you can make ad zones, and have specific type of ads from each advertiser be placed in that zone. So, you could have a text ad rotation, an 468x60 ad rotation, a tower ad rotation, and more.

Though the majority of the advertisers that I have seen, has to get a lead or a sale through you before you get money.
They do have auto targeting ads (currently in beta) that is similar to google ads being automatically displayed based on content, but I have yet to sign up for that part of their programs.
