Firstly, if your father owns a company that has a yearly revenue of $2m, why exactly are you here asking us on advice?
Nonetheless, ontopic:
I personally would recommend the Business; Also, you have to decide yourself, because Business and Law are two completely different subjects; In law you learn about the Romans, you learn lots of history, whilst in Business it's more of math and such. You have to ask yourself, what you want to do.
Be the lawyer/director of a company? You would be an executive and a one many lawyer crew of a company which makes a revenue of $2m. Aha, seems about right....
I say business.
Edit: You already made a thread before where you said you wanted to do Law and were looking at some online stuff; How come now you're asking whether you should study law? (just curious)
