It will probably pay off well for you. You seem knowledgeable, you obviously care for people, and you find the subject matter interesting.
If I coudl make one recommendation, adn only one, it woudl be to never oversell your services, because that breeds dissatisfaction. I had a disappointing experience with one immigration consultant, who promised he was quite experenced with Chinese clients' needs. I specifically mentioned the difficulty in accessing services like translating and notarizing documents. There were other services I'd need, of course, but I used these as examples. He assured me that all would go smoothly, but first I needed to retain his services with a cheque.
Well, once he had the money, he proceeded to tell me to look for those services on Google, that he could not possibly be familiar with all services in all countries. Maybe so, but I felt he had mislead me, and our professional relationship was strained from that point onward. And in interviewing other consultants afterward, I found two that knew quite a lot about China, and would have been better choices for me.
The old business axiom, "underpromise, overdeliver" is always good advice.
Good luck to you.
