Wanting to finally start blade-smithing/blacksmithing hobby dream... Advice and thoughts? (No experience)

Posted this in another reddit and thought I'd ask here as well to get as much advice as possible.

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.
