Need a clone of appswith.us / exopoint.ch

Hello there everyone, What i would like is to have a similar website as [login to view URL] or exopoint.ch. I will provide full web design i would like to have (as ready html/responsive). I need you to build back-end for android application to work (fill in data for conference, hosts, maps, etc etc.) I won't be selling any tickets through this, so do not even try to include that feature in script (app). I need android app related to this as well. Please offer your best price!
