Joomla Community Website

I need the assistance of a Joomla developer to help me put together a very professional online community using the "Joomla" back end. Purpose of the website: The site needs to be designed as an ad revenue sharing e-zine. People will sign up with the site to become an author, build their profile including their Google Adsense Publisher ID, Amazon Affiliate ID, Clickbank Affiliate ID and Ebay affiliate ID. For every approved article they write and that gets posted on the ezine as content, will earn the author 1 point. With the accumulation of points to certain milestones, the author will earn certain percentages of the ad revenue from their posted articles. Starting at 10% after 5 points, all the way up to 50% after 100 points. There are many plugins and extensions for Joomla that are pre built to achieve these functions to a certain extent, but they will need some tweaking to achieve the full functionality desired. There are more basic functions that the site will need to have, such as member management for admin, user lists displaying all published authors with their current point value, ad click through tracking, etc. 99.9 % of these functions are already available as extensions or plugins for Joomla CMS.
