For real. Nerdy science glassware is really cheap. I've always used these as mixing glasses. You can get 6 for $20.

You don't actually need a dark room, it's a common misconception. You only need that if you plan to use an enlarger and make your own prints. I don't, but only due to lack of space in my apartment - I scan them in and order prints at Costco or Bartells like any normal digital scan.
If you get one of the Paterson Reel tanks like I have in that photo, you just need a changing bag. Put your 1-2 rolls of film, a bottle opener, a pair of scissors, and all the tank pieces in the bag. Seal it up, pop open the film canister with the bottle opener, then spool the film onto the reels. Put both reels back in the tank and seal it up. Everything else can be done in daylight. (you can skip the bag and do this in a pitch black room like your bathroom or a closet if you want. I prefer the bag- I can sit on the couch and watch TV while I spool rolls).
Then you're just dumping in chemicals on a timed schedule and then unspooling and hanging them to dry when complete. B&W is roughly 13 minutes a batch at diluted 1+1, or 6 minutes at stock (full strength) solution. Stock just uses it up twice as fast, but saves time.
B&W = developer (12-15 minutes for most films at 1+1 - check the massive dev chart -> stop bath (1 minute) -> fixer (1 minute) -> rinse (2-3 minutes) -> hang to dry (2ish hours or until totally dry).
Color = developer (6ish minutes) -> blix (2-3 minutes) -> rinse (2-3 minutes) -> stabilizer (1 minute) -> hang to dry (2ish hours).
I'm pulling those numbers from memory, but the unicolor kit has a good guide with it.
Stuff you need
For B&W film - you use the 1+1 developer one time (150ml per roll of film) and dump it when you finish. Which means that 1L D-76 pouch gives you 6 rolls of film. I buy mine in the 1G bags to mix up as they're cheaper, but you need a 1G plastic bottle to store it. For color film that kit does 8-9 rolls of film. The bigger 1G kits are more expensive and you can also buy the chemicals separately. Color is picky because you need to keep it at a constant 103F the whole time or risk ruining them, hence the bucket (or a bathtub). Color developer and all other chemicals you dump back into bottles and re-use until it's used up.
The color film process is actually really well documented in the booklet that comes with the unicolor kit.
If you ever want a hands on trial, I can do a video of the process or a demo at my apartment (my fiance thinks it looks like I'm doing crazy mad science stuff every time)

Side note: Since the glass press containers are prone to breaking and replacements are sold, I've often though that it would be cool to design a press housing that works with a cheap, commonly available scientific graduated beaker of some sort.
I'm not sure if they are suitable off the shelf, (do they need some sort of tempering to deal with heat changes?), but if so, I think it would be a pretty sweet angle to approach an improvement from. They are manufactured to relatively exact specs, and they are mass produced and much cheaper than what press manufacturers sell replacements for. Also they would look cool in a press housing imho.
I don't like non-glass presses.
I like these tall graduated beakers. Strong, glass and they look cool ;-)

If you have a small beaker or microwavable glass, you can pour the liquid in the beaker/glass and microwave it to thin out the liquid. This will make mixing it much easier as the VG is not as thick. I say microwave the liquid for 5 seconds per 15mL.

Here. And I suppose you could mix it in a vial, but I doubt it would mix very evenly. Of course there are a lot of steps, you're almost home brewing. It's not as hard in practice as it is on paper. Just follow the directions and you'll be fine.
Edit: you're gonna want this too
