adsense sharing article directory webiste

hello i need an article directory. i wish to open one for a specialized region and niche. to encourage people to drop new content i wish the website to have a revenue sharing feature. the website will display Google ads, and writers can earn a portion of the revenue with the Google's revenue sharing program that deposits 50% of the revenue into the writers Google account directly. examples of a content website that uses the revenue sharing feature is [login to view URL] i really have no preferences to style and design. just something simple and functional as seen on most article directories. but would love to have functional sections such as popular writers section, poplar articles, comments on articles, related articles and things like that. pls quote the least budget that can get it done, i could work with you to add more features along the way. really want it up and running soon within the smallest budget possible. i hear word press can be used and a Google adsense sharing plug-in added open to suggestions, really know little. thanks
