Hi there,
This is melinda here. We are a team of Unity 3D designers and developers. We can able to create the VR using Vive VR integration. We have good hand on experience in creating both AR and VR.
For your game floating bubble pop, do you want the UI designed as well? Also will you send all the assets? or do we need to create from our end? For deployment do you want to deploy it in the production also do you need the source files in unity.
We have developed for Vive, google cardboard, occulus and gear vr.
I will wait for your reply, thanks.
