Possible Cover/poster idea! (Patreon)

Something I started yesterday, a random image of me and my partner Torpedo Shark (aka Torp) looking dope! I would love to sell posters or something printable someday, but I wouldn't know of a place to do stuff like that and make something that large to be placed on a wall. Anything on how to pull off something like that?
