Final Retouch to an iPhone app graphic design

Hello, At this project I will need a professional graphic designer to design in Photoshop the screens to an iPhone mobile app. Please notice that you will get a very detailed wireframes document which also, already includes the main line of design for the screens, also fully layered PSD files of each screen, of the current design would be provided. What I need it for the designer to make a design keeping the same look and feel as the current design. But the designer would have to make a set of new PSDs for the new design, adapt them to an iPhone 4/4S resolution, and later also cut the screens for the mobile app developer. The app contains 8-10 different screens, but some of them have several modes in them (means some internal part is changed). At the end of this project the outcome should be: 1) Photoshop (PSD) files of each screen and each mode. 2) Cutted PNG files for each screen, as for the request of the app programmer. Again, please keep in mind when considering this project, that most of the work was done, since all the screens are already designed, but they need a retouch of a professional designer, adaptation to an iPhone 4/4S screen resolution, some icons needs to be switched, some layers needs to be aligned better, some graphical suggestions from the designer would be appreciated and etc' Wireframes document and an example of the PSD for the screens would be provided for selected applicants. Thank you and good luck.
