I did it for about a year or so, when I was in IL. I will say this from the get-go: be prepared to spend a lot of money, for a very slow repayment cycle, if you're not doing this at scale, and if you're not doing it in a place where you have enough light to suit your needs. Otherwise you'll find yourself in my situation, with the $800 green pepper.. which, was delicious, and probably one of the best I'd had. I just don't want you to think you'll end up saving money, because you probably wont.
Okay, on to the fun stuff. So, on reddit, you can check out https://reddit.com/r/aquaponics. They had a decent enough community there. The other big resource that I was familiar with was https://www.theaquaponicsource.com/.
For my build, it was pretty simple. I got a 55 gallon barrel, cut the top third off, flipped it over, and filled it with media. Then I added my bell siphon, pump, and whatnot, and I was good to go.
The whole setup, for me, was pretty cheap initially. I was in a 5b zone, right outside Chicago. So I had to keep everything indoors, and I had to make sure that it had proper lighting.
