Create iOS News Application

I'm looking for a developer to create a niche specific news application. The app will grab the feed from Google with the API. Must speak fluent English. It must have a Photos tab, which grabs photos from the Google image search for the specific niche, a Videos tab which grabs the videos from YouTube/Google videos for the specific niche, a News tab which grabs news about the specific niche from Google News, and finally, a Settings tab which includes several changeable settings. The app must include the ability to turn push notifications on and off. The notifications will be sent to the user when new articles are written from Google News about the specific niche. Ads must be implemented into the app. Social media integration must be added. The app must be easily interchangeable with different niches. The UI must be unique and clean, it cannot use Apple's basic interface as it looks terrible. All the graphics from the custom menu etc. must be available in .PSD as well so it can be changed for other niches. Payments will be through milestone payments. Full payment will be funded in the beginning of development and paid within 24 hours of the application's acceptance into the App Store. As for the timeframe, this will be discussed.
