I'm going to sidestep all your questions and ask:

Do you really want to build a business?

Because that is what you'll be doing. You'll be focusing on marketing, sales, and whatever else needs doing, shifting your focus away from software development. Especially as it grows.

There's nothing wrong with focusing on business, but if you are a hacker of 15 years experience, you might really enjoy, well, hacking. And business, while it can be viewed as an interesting system to tweak, most definitely is not software development.

Good point, I guess I would code, just in a lesser amount, and focus more on the big picture.
