Hello,
I will deliver 7 poses with transparent backgrounds (transparent png's). These files will be browser compatible so if you load them with hidden <div>'s using css, you can simply turn them on and off as you need for your presentation via javascript or css:hover methods.
The poses will be as you describe, of a androgynous model wearing dark-grey skin suit (like a wet suit). However, the position of these models regarding orientation to the room and camera will need to be clarified. I was unable to view your sample room file so I cannot determine if the poses you describe will be obvious in terms of placement and orientation, however I can promise you will get what you want regarding scale, orientation, pose, lighting, and clothing.
Sincerely,
James Scott
