VR App developement for Oculus Go

We are a small start up. We need an Oculus Go app developed in either Unity Engine or Unreal. The purpose of the app is to demonstrate the usage of our product(more deatails about product on request) . The scene should show the machine about the size of a refrigerator. The scene needs to be a lab/workshop type surrounding(~20-40sqm) with at least one or two workbenches + a shelf. A Cad model and drawings of the machine will be supplied later. The machine has two doors which should be openable in the app. Behind the doors are 3 to 4 components which are removable. There needs to be interaction using the Oculus Go controler and the shoulder button to remove these objects and place them on one of the workbenches. Two of the objects need to first ahve a sliding animation in one axis befor they can be removed. Inside the room should be a shelf which contains at least one of each of these removable parts. The user can use the touchpad of the Oculus Go Controller to walk to the shelf and pick up a replacement part to insert into the machine. On the machine is a ~10 inch touchscreen. There should be the possibility to have some sort of clicking interaction with the elements on the screen. Predesigned screens and menue logic will be supplied later on. In addition to the lab/workshop room should be a second room wich should then house a larger ammont of the mentioned machines in the room. Layout of the room will be supplied later. It is required that the app runs on the Oculus Go VR device with headtracking. The Oculus Go controller needs to be seen in the scene just like in the Oculus Go main menu. You should have either an Oculus Go or GearVR for testing and debugging purposes. We are on a tight shedule. The app needs to be ready on July 16th. It is however required to show a preview befor this date. The screens for the HMI interaction will be supplied relatively late so they might have to be implemented after the 16th.
