Ask HN: Great startup idea, but cannot solo

Assume for a moment that you have a truly impactful (valuable for people) idea that solves a major problem (and probably saves $$$$ which == $$).

But you are experienced enough to recognize that you lack some significant skills necessary to solo-build.

Where do you start?

There are countless "startup schools". Some expect a team and MVP for entry. Some appear to allow anyone with an idea; but some of those may be sketchy or innefectual.

If I said, "I have an idea which will make tech hiring many times better for candidates and companies!", which startup school/group/mentor should I aim for?
