Write an iPhone application

Hello my name is Gilmar Blackwood The project I would like to hire is building a website that’s all about promoting upcoming music, and upcoming talent. The website will be mainly driven around a radio station that would be the primary promotion service; I would like to offer to my customers. (The radio station I will register) The online radio station player will sit right inside the website like an embedded player interface. Customers would listen to the exclusive music being promoted. From a number of ways, (This I need developed) Social media integrations ECT, profile listing of registered artist who use our service as a platform I would like the website to also be accessed from a mobile phone, with its own unique app icon (this I can design myself.) Now the uniqueness to my website mobile app idea is that it’s a radio station that a rap artist can instantly rap on from where ever they are in the world using components on there iphone ect. I need a developed program that will allow group rap ciphers to happen over a system which is like a group chat. The API on the phone will allow invite –the invite will have time to record using the voice note recorder, and using the headphones plug-in The user can listen to an instrumental while recording in the mic recorder while the media player records then plays back. The users are all on a time attack, of limited amount of time to spit lyrics. The listeners will be able to like currently listening tracks or records and this will top up the artist music rating each time.
