Create an iOS app with a map with pinpoints + QR code scanner

I need an app that looks like this: 1. Show an app with pinpoints added by an administrator 2. Show an icon in the bottom, that starts a QR code scanner. 3. The QR code scanner should open an URL, and it should be easy to go back to the main screen with the map and QR code scan menu button icon. 4. The map has to show users current location. 5. The app has to be native iOS, and I need help to post it til Mac App Store To ensure you have read the specifications, I will only look at the bids starting with "I understand the task".
