Fantastic job! It must take a great deal of skill to make a machine like that, so congratulations.
Have you ever considered the possibility of building more of these for sale? The only comparable equipment I am aware of are the whole-body beds such as Thor which can sell for up to $100,000. If you were to sell these at a much more affordable price (maybe $10,000), then more people would be willing to buy them and then this could bring in a significant source of income? I am not sure about the logistics of how you would transport them, or health and safety regulations etc. But it may be worthy of consideration for the future.
