I was thinking of an ad revenue sharing scheme for my website, where users can enter their own ad code that will display in certain sections of the site that they are responsible for. However, none of them own their own websites. Are there any advertising companies that they could sign up to without having their own website?
This website allows many different types of advertising, but I think they just upgraded there script. It would be worth joining and listing your services. http://I-click4cash.com
