Here's a bit of advice...I also did this for a while, and I actually chose not to monetise my YouTube videos... why? Pissing 10,000 people with adverts just to make a buck (literally) didn't seem worth it. Tried the Patreon route as well while I had 2.5K subscribers - got maybe 3 of them willing to pay. USED to make money through Apples iTunes back when people actually downloaded the tracks they wanted. You could get as much as 45% of each track (about 58 cents from a $1.29 track). Now that Apple Music is streaming... for the exact same amount of money - you now need to have 165 people stream that track just to make that 58 cents. Apple Music is killing independent artists who depend on that money. YouTube Premium is hoping to destroy the money streamers make by getting people to shift to YouTube Premium - that way, YouTube make MORE money from NOT shovelling ads in front of everybody (who would have thought). I'd say you and I got into this line of work years after it was profitable. While I'm lucky I have a full time teaching position and love the art of actually puzzle-solving students mistakes, the problem is a lot of the time you don't get the appreciation in the internet as you'd like. I did it as a hobby just for the fun of it, but there's no challenge in it for me in terms of the arranging side of things. I can do it with ease, and I've proven I can do it to the rest of the world. Sorry to be so glum.
