iphone app, prototype

It's a faily huge project, but for now we start with prototype. The overall and complete specifications is being processed, but for now a protutype is needed for sale purposes. I simply need to take a picture from camera, and comment on the picture. And another screen for showing a google map, the map could also be hardcoded for now. So, I'm looking for someone who could work on the project for long time, the details will be given as it gets finalized.
