Simple iPhone APP

I am looking for a developer to create an iPhone/iPad app based on an idea and concepts that I have. Future updates to the app and future projects will also be given to winning developer so a long term work relationship is desired. Here is a brief description of tasks and requirements: 1. App is geared towards improving user experience and should be very simple to create if you know what you are doing. 2. I can provide task flow of app and will help with the interface design as I am a graphic designer. 3. Developer should be member of Apple Developer Program. 4. Full payment will only be released (paid) when the app is on the official App store. 5. You should have at least 1 app on the App store to bid on this project. Please PM me samples of your work. 6. Developer must have an open line of communication through email and instant messaging (phone access is a plus). 7. Developer must be willing to agree to a confidentiality agreement. I look forward to working with you and this should get fun!
