My goal is to work 10 billable hours a week. Of course there are the non-billable hours that you do to keep your business moving forward or prep work. But, yes, my initial goal is 10 billable hours weekly.
I'm just starting and don't have any clients yet, so it is good to hear that you can bill 30 hours a week. That gives me hope I can make a living doing this.
To get to my comfort zone my goal is at least 30 hours per week of billable work. Seems about standard. I can survive on that and still maintain an order to my life before having to outsource work myself.
