Design graphical user interface design Apple IPhone

Hi, we are looking for a skilled and experienced designer who could deliver several graphical user interface designs for Apple IPhone apps. You deliver the design, we do the coding. We have plenty of work to be done and are therefore looking for a long term business relationship. Requirements: - main PSD (structured) for each screen in 960x640px and 480x320px reolution - each graphical element as PNG in 960x640px and 480x320px reolution - 8h per day availability via Skype - focus on details and quality work - 100% delivery in time - language skills: english (fluently) + optionally german In order to get known to each other, we start with one home screen for one mobile app. That job consists of three tasks (current design will be delivered): 1. The existing design of that screen needs to be rebuilt (technical requirements see above). 2. After the design has been rebuilt, two navigation icons within that screen have to be redesigned (the current ones are a bit outdated). 3. In the top navigation bar, two logos (will be delivered by us) have to be integrated into the design. As I mentioned above, this is supposed to become a regular collaboration. At least 20-30 tasks like this (rebuilding an existing screen design + changing and delivering some logos / navigation elements) will follow shortly after completion of the first screen.
