I think you need to find your own answer to this, and your answer will determine if you have a product. In other words, you probably need to build contacts with businesses and get them interested in possibly hiring from your boot camps. Then you probably need to find some brave souls who are willing to go through your first round (maybe only charge if they actually get a job?) and see if you can land jobs for these people. If your placement rate looks promising, then you may have something. I imagine that's a big part of the value these boot camps bring to their students. They probably have awesome contacts, and building those contacts probably isn't easy. Building these relationships is probably more important than the actual teaching of the courses.
