Bet system

Hello freelancers, I need a website, iOS and Android app, fb/twitter/email login, as follows: The site is a closed bet system. There will be unlimited bet groups, each one independent itself. The member sign up for a specific group, pays the bet, and in the final the ones who win splits the total amount of the pot. The basic structure I need is: - The home page shows some bets by category (newest bets, biggest bets, etc); - Everyone can open and host a new bet group; - Every bet group must have a host; - The host has a management page, showing everyone in the group, group member contact, informations, videos, public msg (for this group). - The groups must be opened or closed to new members. The host decides; - Every step must be shareable in fb/twitter; - It must also have a member page, which shows his/her progress inside his/her group; - New members pay to get into one specific group; - After a while, the members who win the group bet splits the pot. - Must have a master management page, showing global informations. Basically this is it. More information will be given to interested freelancers. Not necessary to say it is a confidential project, and all information belongs to us. Thanks. Rudolf
