But I had no idea how difficult developing it
is.

The Nikor adjustable stainless steel daylight developing tank is the ticket.
Holds 12 sheets of 4x5 film and about 40 ounces of chemicals.
You load your film in the dark onto a special cage, stick it in the tank, cap
it and turn on the lights!
Proceed to develop as you would 35mm film in a SS tank, inverting the tank for
agitation, etcetera.
Hard to get but it does come up on eBay every now and then. Will set you back
over $100 but you'll never regret it.
