Hello, We need to build and application for Revenue Sharing very similar to [login to view URL] This is awebsite that uses it, you can register and see how it works. [login to view URL] It is a platform where people signup and buy publicity packs, then they have to look 10 ads of 60 seconds a day to earn revenue. So, what would be involved would be: - Login/signup system - Payment processors - user statistics (revenues, ads, balance, etc) - user profile where user can upload his/her documents - invoicing for user buys/revenues - banner system (PTC, PPC, login banners, etc) - page/blog management for admin We are still to decide if building it in a php framework such as laravel, cake, igniter or as a wordpress plugin. *We think a wordpress plugin would be best. The budget in this job is a placeholder. Please let me know your estimates on time and budget.
