The fact that you don't have enough time to do both could be a red flag indicating that the business is going to be hard to scale up to the level you need. Are there aspects of the work that can or should be automated? Are there aspects of the work that should be offloaded to third party services to free you up to concentrate on the bits that bring in the money? Are you charging enough? I ask because not charging enough to cover your needs is a common mistake. Increasing your rates might reduce the amount you need to scale. Do you have enough saved up to endure a year or so of reduced income while you work out the problems of scaling? Figure out the tactics. Plan for the transition. Don't just fling yourself into it. I don't say any of this to discourage you. I hope that, after some planning, you make the leap and I hope you do very well from it.
