UI and graphic designer for simple iPhone app

Hi, We're building a very simple iPhone app, and need to hire a UI and graphic designer right away. I have the main design concept worked out, but need someone to create the final graphics. I have already hired a programmer for this project, and if hired you will be working and communicating with this programmer on a daily basis. I will give full details of the job to applicants I select for an interview. Applicants must be available for an interview on Skype. If hired for the project, applicants must be available for daily communication via email and Skype to provide daily updates and work progress. Please provide links to iPhone apps you have recently completed the design for, and that are currently available for download on the App Store. Looking forward to your bids. Many thanks
