Hide Pro Blog Templates From Sign-Up

Hi there,

I am wondering what method I could use to hide certain "pro" templates from the sign up. I realize there is no way to make pro level specific templates available on the front end; however, I was thinking a good work around would be to just "hide" the pro level ones and have the user contact me, so I could activate the template for them. I just want to be able to have the template already prepared for when they do contact me.

I read this post: https://premium.wpmudev.org/forums/topic/hide-templates-from-front-end-selection - where Vladislav explains you can copy them to a theme folder, but I am unsure how that would work. How would you activate the template? Would the user be able to do it? Would it no longer show up in the front-end selection?

Look forward to your response!

Cheers,
Tyler

PS. Any other suggestions for a work-around here would be very appreciated!
