I started doing it super small-time with my Dad when I was very young, then progressed to tapping a dozen trees and getting 4-5 gallons a year. I used to sell it by the quart to my teachers to fund my walleye addiction.
To start small, all you’d need is a tap, a bag hanger, a bag or 2 (squirrels like to chew the corners), a drill, a pot, and a stove. I guess you’ll need a cooking thermometer too, but that’s about it. Super simple. Its been years since I’ve done it but think the standard tap is a 7/16in bit. Your turkey fryer would be perfect. That way you can do it outside; my mom was not very stoked when our entire kitchen was sticky when we first started.
