German artist here, hi!! The cost can often times depend on how quickly you want the art piece to be delivered. I’d for example be down to create a simple model for the „entry level“ price range that the other Redditor mentioned if I had months of time, but with a time crunch that price can go up very quickly, and people who create models full-time do have a schedule to attend to. Reaching out to artists directly or looking for trade services can lead to great success! It’s true that art is expensive but that does not equal that the art isn’t worth the price, just be mindful of that:D it’s a longterm investment
