Interactive Advertising in-app prototype

Looking for an experienced VR/AR Unity developer to help develop a prototype of interactive advertising elements within an existing 360° video experience for the Oculus Quest. The in-app advertising will appear during the experience and showcase advertising from a travel brand. Users will be able to interact with the advert and "activate" a sponsored VR environment from the 360° video allowing full six degrees of freedom within the environment. Users will be able to collect codes to utilize for future offline purchases. Keep in mind this is a prototype to showcase how it would potentially work and not expecting a full blown back end system. The app "Escape Now" is currently on the Oculus Store.
