Hi, I'm a business consultant (to the optometry field) and my daughter's fiance is in a similar situation. I suggest that you get on a fast learning track on CNC and what it can and can't do. Look for used books on Amazon, new books may be more up to date, YouTube videos are useful and helpful for starting up your tech skills. And, keep your eyes out for classes. As you find out more about the CNC world, you'll find how they're used and which businesses use them. Ask to come visit and observe in those businesses - as a hobbyist, not a potential competitor. The real problem is that once you acquire adequate skills, then you must choose products or crafts to make AND LEARN HOW TO MARKET THEM. I suggest you find a small market (people who need a specialty item that the big manufacturers can't profitably service) and get known, perhaps on Facebook. My consulting business is growing nicely through my contacts on Facebook. You can join groups that are not about CNC, but about the businesses that buy CNC produced specialty items. This will become clearer to you as you learn and study the field. You have lots of years to make this happen, so if you want to make a living at it, use the first couple of years to really learn all you can about CNC, what they can do, who wants stuff from CNC. You have two choices with CNC, make a lot of the same stuff or make specialty stuff for people willing to pay and who don't want to go through the same process you're about to do. The best business I ever got was to find a niche with people who have money and are happy to pay for something they need. For me, it was the smallest but most profitable specialty in optometry, in which there was no other competition. Well, those are my thoughts, putting my woodworking cap down and dawning my consultant's hat. Good luck with the process.
