I already do concept testing/customer interviews for startups, and have worked with a product strategy consulting group that did the whole package for startups similar to what you’re describing. There’s absolutely no shortage of people who want and need it, but unfortunately very few startups have the cash upfront to pay for the hours of labor it takes to create those deliverables. Five good-quality customer interviews alone are about $500 in labor end-to-end, what you’re describing is definitely over a thousand.
So you pretty much can’t set a price that the average startup owner finds appealing, you have to convince them that even though it costs, it makes more sense to pay for 20 hours of your labor than waste hundreds of hours of their own labor going in the wrong direction.
