App for iOS using GPS services and maps - repost

This app will need to do as follows: 1. pinpoint where you are located on a map. SIMPLE. 2. Let your friends know where you are. SIMPLE. works a little bit like this The owner of the phone activates the phone by pressing down on the volume button and another button so as to send the GPS coordinates to a friend. Need it done in less than 2 weeks. Develop own artwork and screens. Need to be bright, sharp and unforgettable. Will later require the Android version, so bare this in mind now. I can provide: 1. Design ideas 2. Detailed brief if we get talking and we like you. Great people to work with.
