Client asked me to create pyramid scheme script. Basically, you purchase points that you can resell. Higher you get in the pyramid more you earn. You can use php/mysql and html5 to do it, i will give to you access to my web server if is neccesary. Mercadopago as virtual payment service. [login to view URL] 0) user login via facebook or twitter 1) user buy points 2) user resell that points 3) the admin get 30% of fees for every transitions. IS NOT NEEDED THE DESIGN OF THE WEB, ONLY CODING
