Basic iPhone Application Needed for Kid Travel

We are looking for an experienced Obj-C programmer who can develop a native iPhone application for us. Our mobile application is a Children's Travelogue (travel ? or vacation tracker so to speak) which will allow children and parents to track all the wonderful destinations their children travel to. We envision an application which will show maps with pin drops (similar to the old cork board that many of us had hanging up in our house of our family vacations.) Each child in the family will have a different color pin. Tapping on the pin can bring up a page of vacation details, spanning from: location, date, age of child, mode of transport, accommodations, and the ability to upload photos from a photo library.? The main view will essentially be a picture of a map (users choice of three, US, Europe, World) with various tappable pin drops, specifying vacation, and obviously color-coded for each child, just like the old cork boards. Functionality should have easy ability to Add Child, Add Vacation or Trip, See a List of destinations, View Map, Current Location (for adding on the fly), ability to export to email, etc. Must have clever, creative child-like design, and a simple, useful UI.
