Suppose you have a budget of $20.
Do you think you will find good artists working for that fee?
I don't think so, unless they are working to prove a point -- that humans can be as good as AI.
And that's the problem:
Humans can be as good as AI, but they are much more expensive.
Maybe you have a friend that's trying to get started in design and could do a favor for a chance to build a portfolio.
