Amps no idea, but unless you’re able to everything yourself, it’s likely going to be cost prohibitive anyways. let’s say you could do it cheap for a few hundred dollars, you’d have to shift so many units to just break even, i can’t imagine it’s worth the hassle.
maybe if you could set up a collective where you have several good artists, a mastering engineer, maybe a couple of people into graphics/video/etc. and you’re all willing to work for the greater good, it could be viable. maybe.
