You set your goal to $347 and have exceeded it. But there are also tiers for as high as $1042. How much does this project really need?
I see this as a business with a franchise model, you need software , you need hardware, but you need a trained person to quickly model the space.
I was taking pictures of a car the other day, met the owner, and sold him 5 pictures for $10. That is fun but not scalable. A real VR photography job has to pay more. Working indoors, for instance, I am always trying to manage my own shadows and reflections. Indoor scenes often have have lighting anomalies that are unacceptable when I see the images and I have to change the room if I want to get the images in my mind.
