Wow, in switches alone this would cost me $1200! Which actually isn't that bad for a one off-like this with easily available components - I've seen worse. You can of course take your chances with Aliexpress Specials but be warned: some of those cheap switches are cheap switches (sometimes, they're barely even switches). And you won't be getting them inside of 2 weeks. I think I would have tried mechanical keyboarding switches that can take an LED and a clear keycap. Not really the same effect, but you could probably have gotten out to 24x24 for the same price.
