Which Vocal Academy Looks Better?

I'm a 13 year old girl, and have ALWAYS been passionate about everything that has to do with music (especially sining). In fact ever since I was 3 years old I was singing and talking about being the next big thing. My goal in life is to be a singer/songwriter that will go up in history along with the greats of music. I have been taking voice/guitar lessons for about 7 years and am now taking piano lessons!

So! I've been thinking for a while now about a more serious vocal training academy. And I found what seems the best academy that offers vocal lessons plus acting lessons (which I'm also interested in). The academy's website is:

1) http://www.duet-vocal.com/ (Duet Vocal Academy)

Bottom line is, that since I live in Northern Virginia there isn't 'many' vocal academy's that offer good lessons. So, if someone could help me by telling me a good company in Northern Virginia that offers preferably voice/guitar/piano lessons (especially voice). Anyone know any off the top of their head?

*Then compare your result with the Duet Vocal Academy's website, and tell me which one you think would be best at helping me shape myself into an amazing musician! =)*
