If your vision is truly so all-encompassing, maybe that's the thing you should work on selling -- but not to investors; to the people you want to work with. Solve your HR problem, get some co-founders, and get going.
That's more or less the plan. Convince some key people, maybe raise a seed round that pays for a couple years of formal pre-production, and very delicately snowball into a dream team contingent on further funding.
Co-founders can't work since I've been at it nearly a decade, but that's more for control/singular vision reasons and not equity.
In the mean time, I'm just thankful to be alive and working a full-time job to get there.
