Design an App Mockup

I have an iphone app that is still in development and I am looking to redesign it. I need someone who is capable of bringing their own ideas to the project also. I have a few inspirations from app screenshots but the majority of the design will need to be drawn up in photoshop. I am looking for high quality and a very clean design. I have attached a design inspiration in the files. I am looking for an iOS 7 look to the app. There are roughly 15 screens to design. All the functions to the app are implemented so the designer will need to create the design for the buttons along with backdrop and feel to the app. Please contact me if you have any questions regarding this project. I am looking for someone to start work straight away and to finish it as soon as possible. All mockup screens must be made in photoshop.
