Design multiple screens for iOS app.

I have an iOS app under development and have already approved the theme and style, but require a designer to adopt this design for all other screens within the app. Most screens are similar and the layout and positioning have already been determined thus reducing the input and amount of creative thinking needed. If you require a breakdown of the project I can provide you with a detailed list of requirements after we've had an initial conversation. A demo of the product is also available and can be presented via Skype. The project can be divided up into sections and worked on part-time as not all screens are needed at once. However you will be required to deliver finished files at least 7-10 days prior to the end of the corresponding development sprint date. Working Photoshop files will be needed.
