Iphone Ui Development

Design an iphone application for travel planning. I have defined the requirements for application and need to assemble into coherent design and flow. It would amount to 50-60 screen shots including all the typical ones you might expect to see including login, create account, welcome, help (though the help might be more screens in production, the basic help and template for help docs count as 2 screen shots in my mind). I am not seeking development at this stage, though will be in the near future. I would work with you on the phone/skype for about 3 hours walking through the requirements that you would use to create a draft set of screen shots and flow for me to review. I would expect 2-3 cycles of design and review before the contract is complete.
