Setting up of Captive Portal on Cloud Server using Chillisoft, Radius Server and Webserver with Authentication to Social Media

I would like to set up a cloud based Captive Portal server using Chillisoft, radius server and websever that can allow the login page to be easily updated. Login page will request that Users will allow information collected to be used for marketing purpose, and for them to agree to terms and condition of use of the public wifi service. Authentication for access will be through social media and/or SMS. It will be use on multiple locations, and configurations on the router will need to be advice.
