Your plan is nice, but you'll never get to 5. You will most probably get stuck in doing client work with that strategy.

I would rather continue in your current position and prepare everything to not "Switch from contract work to our products gradually" but switch from a known and secure context to your new product. Either gradually or abruptly if you have enough cash.

Haven't replied to the other questions due to blocking point 5. But mentor and coaches are great to have an external point of view : try to use them wisely.

Good luck!
