Not too hard at all! I have a 5 gal bucket with lid that I got for $3 or so at Home Depot. Buy some liquid dev (HC110, Rodinal, Ilford), buy some stop $10, or use a water stop, rapid liquid fixer and you are done. Throw out your dev after every run, keep the left over stop and fixer in a collapsible container or glass bottle till exhausted. The rest is history. Just need a tank. If you search craigslist, there are many garage sales this summer with tons of tanks. I found a few stainless tanks and reels for next to nothing the other day. Load your film in a dark closet, bathroom with blanket/towel covering light. Crack the 35mm spool open with a beer bottle opener.
Get some rubber gloves, apron, goggles of course. If you decide to get dry dev and fix and want to mix up 5 liter amounts, sure that is great, just the volume of items to store will might out grow that 5 gal bucket. So get two and stack them when you are all done.
Yeah you will need some graduates, mixing rod, etc. Lots of this 'consumable' stuff like I said are going next to nothing on Craigs.
I am sure others will chime in with great ideas! See what fits your situation best, appropriate, ask questions, its such a joy to run your film!
When you are done, lock up your 5 gal lidded bucket(s) in a cabinet away from kids/grandkids or whomever should be near. You can do it so simple for not much, maybe less than $100.
You can do it!
