Finally want to start bladesmithing....no experience...advice?

So I'm finally going to bite the bullet, and get into what I've wanted to be my dream hobby for a while. I want to start making blades, and not just blades.....this is going to sound silly but.... keyblades (from kingdom hearts in case ANYONE doesn't know). I want to make ones from the games, custom ones, and ones I have ideas for. I also would learn general metalwork/welding and maybe even some woodwork to kind of expand the art of it. I just want to be somewhat different then the people who just 3d print them, and actually make some semi real-ish keyblades that are very visually stunning. And of course I would eventually make Video Game weapons as well, and just normal blades, maybe try to sell some if I really want to, but this is mainly for fun and to collect. I would even just stream the process of making one just because it's something to do.

This comes with the issue though....I have no bladesmithing/blacksmithing experience at all. I'm 32, fairly good build for doing semi-hard work, and I have a decent amount of free time after work. What do I need to do to get into this? What kind of classes do I need to take, tricks of the trade do I need to learn, how much time should I dedicate to the starting process of learning everything (before I obviously just practice vigoursly on my own). Obviously I know this isn't an instant process, and it could take many years before I get good enough to even attempt to do it decently regularly...but I just want to get started on this. I've had this idea/dream ever since I was 13, and thought I'd finally act on it. What do you guys think? Any advice would be hugely appreciated.
