I have just a couple of sets like that. Check this link out:

I was going to shoot all my best models like this, but got some other orders and forgot about it... I can do affordable exclusives like this, or may be partially exclusive content if you can't afford exclusive... I'm not sure this is exactly what you you need, though. Anyway, hit me up if interested...
