I need an iPhone/iPad app designed

I need an iPhone/iPad app. I would like it designed. I am looking for an experienced and creative developer that is capable to create the user interface without the actual logistics of the app. If we like the work, we would love to hire you soon again to accomplish that task. As of right now, we just need someone to design the interface in order for us to pitch the idea to potential clients and investors. Your major task will include mimicking an existing iOS application and including some interface enhancements. You can feel free to improve it to your thoughts and feelings as well. It's a pretty simple and straightforward app that includes: - a leaderboard - drawing areas on google maps - news, messaging and incentive system - a bill calculator - agreements sections, including being able to sign a contract - etc. Please, let me know if you feel comfortable helping us and we will show you the app we like mimicked! Thank you, Chris
