Well, finding a contractor that's done one is not going to happen unless you're in a major market. Key is show them the pictures and draw it out for them. And then supervise. The hardest part is the skinning with 1/8" plywood. Read some of the other questions I missed so here's a couple of them answered to the best of my knowledge...The floor lighting is necessary to maintain an evenly lit seamless surface. There will be shadows from your subject. Lit with the soft fixtures in the list the shadows will be pretty mild. You can pull your hair out trying to get rid of them or succumb to the fact that shadows are natural. If they bother you, photoshop them out.I think you are overanalyzing the lighting choice a bit. All the links I gave will provide plenty of light. Key is even lighting and that means placement must be right. Then you can adjust exposure to bring it up or down to where you want it. If I use my mobil greenscreen or white paper or other background, I spend time before the subject is there getting the lighting even. Then I work on lighting the subject. Ive already adjusted exposure for the background so it's a matter of getting the subject to look right with those exposure settings. All in positioning those lights. Not difficult but the first time you do it, it will take time. Since it sounds like you will have a repeatable situation, you can continue to tweak as needed and eventually, you will know all your camera settings and where to put the subject lights without even thinking about it.This has worked with both video and photos.
