You could provide them with the VR camera equipment, experienced crew, and training/resources to make the highest quality VR scenes. Help them shoot their first few scenes, working out a deal where you provide the equipment, production expenses, and training for them with a contract that they must list a certain amount of scenes on your site. They can of course cross list them on their own sites as well, maybe after a set period of time, so you have an exclusive listing. They then own the content under their studio and you've helped onboard them onto your platform so they can list more content over time if they want now that they are up and running making it. You could maybe start with a set number of scenes. The benefit to SLR is it will draw in all their followers to the SLR platform.
I'm curious why something like this hasn't been done yet and why a lot of the major porn studios and famous directors/male talent aren't making VR porn.
Some names that come to mind....
