I have done quite a bit of tutoring myself in academic settings and briefly on the side for finance professionals, but I have never thought too much about the business end of things. Your list of prospective "offerings" seems like you have a full service type of model in mind. I think an instructive excercise would be to inventory all other forms of competition in your "area" and position yourself accordingly. The full service model might be difficult to pull off initially, particularly on the college counseling end of things. This business week article I read recently will give you a good look at what the high-end of that market looks like.
