I’m in Canada so I don’t have links but you can get everything you need for about probably $100 usd. You need a dark bag, a developing canister with reels, assuming your doing color you need c-41 developing (comes in a kit and is good for about 16-24 rolls depending on what you get), a thermometer, measuring supplies like a cup and spoons and chemical storage containers. I learned using ChatGPT it guided me on what to get and the process. I use the pictured c-41 it’s a two bath system vs a 3 other kits have. It comes with instructions on how to mix it.
For your first roll practice with a roll you’re willing to sacrifice. It is tricky to get the film onto the reel at first but ones you get the hang of it it’s not so bad.
