I wouldn't make any decisions while burnt out. Take some time and recover.

Then I think you need to think about where you want to go in your career. Do you enjoy development and want to do nothing else? Don't start a business, because you'll end up doing a lot of other things. Are you interested in the control and passionate about your solution of your own business? Then start a company.

Note that there's many other routes, some outlined in other comments. In particular I spent years as a contractor/consultant on my own. It paid the bills and gave me a ton of freedom.

Is a good one, though high level.

For nuts and bolts I don't have a good recommendation, other than take other software contractors to lunch and take a lot of notes.
