"Learning by doing is always the best way for me."
... we certainly share this in common. But, it is concerning to read this post, if I were to be honest, as it sounds as though there are several caveats in it which may or may not turn out in your favor.
Whatever the future may hold, though, in setting up a new Witness server, I know you will be giving it your best effort. I hope you will be seriously considering and successful in leveraging the work and experience base of others, who have gone ahead of you. To maximize your chances ... Setting up a Witness server is one thing - I believe you will (or at least you should ...) generate a lot of support, if you make an announcement.
Having it prove to be a profitable venture is an entirely different matter. I do not have the experience base of others. But from what I have read through my 1-½ year "journey" in here is that many desire this outcome, but few achieve it.
Whatever happens, you have my full support!
