Create a Software for WiFi

We need a software that works like a hotspot for a WiFi network: 1. Client connects to WiFi 2. Client is redirected to a splash page in his internet browser 3. Client makes login (via facebook, twitter, etc.) 4. Client sees ads 5. Client is free to surf the web We need to keep all the clients information in the cloud. The software we need to create is similar to: a) Purple Wifi: [login to view URL] b) Antamedia: [login to view URL] c) Socifi: [login to view URL] We need the software to be multi-language (at least English and Portuguese) We need an APP that can be freely downloaded in the APP Store or Google Play Store along with the software. This is part II of our project.
