But that brings up another question; how much do lessons usually cost?
If you organize a time to see a well respected teacher (preferably a RICH teacher), and plead your case well, you may end up getting free lessons. Yes, that's right- some teachers not worried about money, or have too much free time are willing to secretly teach you for free. This is what my teacher does. He, himself is an immigrant, and knows the difficulty he had to face to get to where he is, so he does teach immigrants (like himself) for free- feeling compassion- It's like doing Volunteer work..
Another thing you might try is learning a different (cheaper) musical instrument. The basics of music learned on any other instrument can be easily applied to the piano.Anyway, that's what I'd do. hope I haven't given you any foul advice.
