Understand the idea now. It isn't so much different then the model that article sites use. Content providers post an article (provide content) and get the opportunity to link/ad back to their businesses. Then the article sites make money by having ad network ads all over the place. Maybe consider ditching the $1 and introducing your own ads. That way you will get a lot more content and you won't have to worry so much about building a relationship with your advertisers.
