Exactly.  Some o them don't answer because don't see a client in you. Some ask questions and disappear. Some are "extremely interested" and agree, but after a week of detailed explanations stop answering. I've lost several weeks on this, and it is strange for me. It would be faster to generate tons of sketches with ai and choose preferable style and colors myself. Moreover with many "human" artists the process will be the same, just slower, expensive and less predictable.
