I wrote the complete application to C4 Adevrtise to cretae a network marketing, banner advertising and advertorial solution so that people can earn money from marketing their own business with their banners and work their way through stages for rewards from the community building. 

The system earns people money for reaching different tiers in the membership and offers them more advertising as they progress through the system. The advertorials allow members to write their own business review and indexes them into the search engines.

The solution was written from scratch and has several hundred members from around the world advertising through classified ads, banner advertising and advertorials with commissions run and paid weekly.
