I like your entrepreneurial spirit! I have always tried to find ways to earn a living as an artist, because image making is what I love to do. Now I do digital art. And I could imagine it engraved by laser on metal.
The challenge for digital artists is how to sell their art in a format that becomes an object an art lover would want to buy. Giclee printing on paper, special inks on canvas, and 3D printing are some of the methods that have been used to solve this situation. I could see your laser techniques as another option!
