I need iOS and Android news reader app with push notifications for Joomla based.

I need an iPhone/iPad app. I would like it designed and built. I need iOS and Android app for reading news and recieve push notification from my existing joomla based news site. iOS and Android app are identical both layout and functionality. It should have : 1- main storyboard to display news title + first few lines of the news, then break with a jpg image, then follow by other sequences of older news and jpg breaks. 2- those jpg breaks are replaceable from website or database table. 3- load more stories on scroll like facebook app. 4- click to read more on desired news story to display full contents of news with posible to play videos from onsite video upload or video sharing sites, save photos and also can share the news to social medias. 5- on reading detail of news, admin of joomla site could change jpg images for headers and footers ( those image will be displayed to all news post). This feature is add on to joomla site not app based. I will detail more about this.
