All three of these ways are grammatically correct:
¿Va a hacerlo usted? "Are you going to do it?" The most typical construction.
¿Usted va a hacerlo? "You're going to do it?" This is the same word order as the corresponding declarative sentence, so it's similar to stating something and then asking for a confirmation ("..., right?"). Like English, it relies on intonation to convey that it's a question.
¿Va usted a hacerlo? "Are YOU going to do it?" (as opposed to someone else) By moving the pronoun closer to the front of the sentence and putting it in an unexpected place, it emphasizes the word more.
You can also omit the usted entirely if context makes it clear that you're not talking about somebody else. If context is clear and you use it gratuitously anyway, it ups the respect level slightly.
