Iphone App

I need a simple iphone app built. Serious bidders only as I am looking to continue to update the app as it grows and build additional apps as well. I am looking for an app that has the following capabilities, Sharing, Achievement gathering, push notifications of reminders, rss feed, social media tab to view company you tube channel, facebook page to like, twitter page to follow, ability to play custom music (start, pause, rewind, forward capabilities) in app purchase and the ability to send specific custom messages to all users that are using the app. More details will be provided on first contact. I also need the app to be submitted to Apple and so on in order to get the app up on the App store. Thank you and I look forward in working with serious and professional bidders :D :D
