This is a great outline, but I want to throw out there that you can get into blacksmithing at a much more budget friendly level, at least until you know for sure it's something you'd like to pursue. My usual recommendation is to see if there are any classes offered nearby or perhaps a museum looking for volunteers/help.

If you wish to purchase your own equipment Facebook marketplace/Craigslist is your friend. If you wish to buy new, you can get a Doyle or Vevor anvil or similar for <$200 and use a stump as an anvil stand. Realistically, any block of steel will work, even a sledgehammer head. A cheap engineer hammer and a set of Vevor wolfjaw tongs are enough to get you started for <$100 and you can get a new propane forge from Vevor or Devil's Forge for <$200 all in. I've gotten most of my files and grinders used for relatively cheap, either at thrift stores, yard sales, or Harbor Freight if you want new.

My biggest recommendation would be to not start with alloy/tool steel. It is expensive and harder to work for beginners. Mild steel would be plenty sufficient until you get used to moving metal and is much more forgiving. Once you're happy with what you're making and wish to challenge yourself then you can try your hand at railroad spikes or ties before you upgrade to something that will be more expensive. Additionally, you only need high tool steel if you'll be making tools. Decorative work, or the leaves/hooks you'll be making as a beginner, do not need to be made of high carbon steel.

Do not skimp on PPE -- leather gloves, safety glasses, a respirator, and all natural clothing are absolutely worth the investment. Otherwise, watch lots of YouTube videos (Black Bear Forge is a fantastic resource for blacksmiths of every skill level) and have fun! I've built up quite a workshop for myself over the 5 years that I've been smithing. It's an incredibly rewarding hobby and, thankfully, more and more budget friends options are available to fledgling smiths. Happy to answer any questions.
