Well, your customers are mostly going to be human. For instance, I'm a human and I'd love to spend $500 for someone, who knows what they're doing, to coach/guide me over chat/email through the process of validating a business idea in a high quality way. I don't think it'd come down to more than 5h of work.

One way of scaling it that has already been done is to use the customer's humanness, by selling a book. That scales. Now, if the price point is $500 for a small but high quality business idea validation, what can you do that's better than selling a book on how to do it? Could you train coaches, who then can bill over $100/h and let the customer execute on it? Willing customer right here.
