Evening Gents!
I think it is possible to start with a low budget, especially if you already have some sort of customer base. At the end of the day, not many customer can tell the difference between 2 cc machine, and most of them only care about the results. As long as you can satisfy the customer and leave a nice result no matter what you use. IMO you have to concentrate on training and marketing. You can spend a fortune on equipment and make no money if you can not sell your service.
