Printing art and selling art

So, I've gotten back into my art since losing my job and I've wanted to try and attempt going somewhere with it again. I tried doing the art thing straight out of high school and before I had gotten my job, because it has been my dream since I was little to be a successful artist. However, I got nowhere with it and hardly made any money. Now, I'm trying a lot harder and trying to find resources to be more successful. I'm interested in learning how to go about getting prints of my paintings made and I'm also considering opening up an Etsy shop, since I'm getting a little more feedback than before. So, if you have any advice, I'd love to hear it and it'll be much appreciated❤

Also, here is some of my work. I draw too, but have taken a break from it to improve my painting
