You should definitely post this in here: Job Offerings - Unreal Engine Forums
Or request a mod to move the thread over there. I think you might have a much easier time since this section is more about discussing HOW to create content 
Personally I lack the VR end or I would be happy to help out. But definitely try the job offering section. You might even consider contacting the author of one of the marketplace kits to see if they are willing to help work out some changes to the kit for you which I am sure they would if you offer to make the effort worth the time for them.
