app build - ability to take photo and record location

I need someone to write the code for an iphone application. I can design the interface. I would like it to have the ability to be able to take a photo of something, whilst recording the location the photo was taken. I would like the location to be saved as a pin on a map which could be seen by everyone with the application. It would need the function to add a title and descriptive text about the photo. It would be great if it had the ability to publish to facebook also.
