Looking for an experienced iPhone/iOS UI Designer

We need someone who is very experienced in designing for iOS to create a feature rich, nice looking, interface for a mobile app. We provide the User Interface, and are looking for someone with experience to replicate it in graphics and provide for the iPhone. The type of app we are looking to create will be a communication app that is fun and engaging, with advanced features and a social media sharing component. Please reply with a portfolio of examples of your previous work including any user interface or design examples you have done before. If we like your previous work, I will reply and give you more details. *********************************************************** Only user interface for iPhone, not the entire application. *********************************************************** Thank you for looking.
