Create an App

I would like to create an app that involves gps integration. The app is a fairly simple app, but I need an experienced developer to discuss the fine details with. Must have an active app that I can review, I will not select someone that does not have one. Basic features of the app I want: 1. Ability to enter up to 5 phone numbers that the app will send a message to along with gps location 2. Ability to make sure app meets guidelines for app store guidelines 3. Ability to provide support (for pay) after app is launched Please send pm's for questions
