Samsung and LG Smart TV IPTV app

Hi, I need an IPTV app for Samsung and LG Smart TV (Tizen, Orsay and WebOS). I will send you the app design and the app have to work like a normal tv, but for IPTV channels (Live channels, TV Series and VOD). I'm Italian, so I like that also the developer know my language, but it's not a problem if not.
