Cardboard VR application

The project is already conceptualized. I need a developer on board to complete the project. There are 3 main interactions in the app. Navigating the in the virtual environment, Creating audio annotations in the environment and saving the annotations on the server and load them everytime the app is run. It is a small project but has interesting aspects to it. The required assets are already purchased. The audio annotations are simple voice recordings. The user walks anywhere in the virtual environment and creates a voice annotation and saves it as an object in the scene.
