Or more proper: Sumimasen, watashitachi wa NM o koutai de surimasuka?
Though you can probably drop the implied "we" (watashitachi) bit as that feels a little "booky".
[edit] just for future reference if you see the lines across a vowel that just means an extension of that vowel sound (as in the "o" in "kōtai") if you can't type that however you can ad a "u" after the vowel to meant the same thing. so koutai = kōtai
