Yes, we shoot greenscreen and give the customers their choice of backgrounds. We deliver prints on site using Dye-sub printers.
If you don't like the cost of the camranger then you REALLY wont like the cost of that stand. They start at a couple hundred bucks and go up. For your use I would recommend getting a lightstand mount.
My personal favorite is the Grifiti Nootle brand. Amazon link: http://a.co/5p9ZA9E
I use one for my surface pro. It holds better than it looks like it would. The grip itself has a 1/4 20 thread. You could mount to the top of the stand with a umbrella mount, or use the clamp to use on a tripod leg.
