I have won all the three "RashtraBhasha" with distinction in School and have always been around people who speak Hindi all my life. My experience as a orator in college events, debates and street plays has helped my voice to be clear, soft and very audible. I can guarantee you i am the best person for this task.
I am really proud of my national language and will make sure i do not disappoint you at all.
If, like you say, it is less than two hours work, i can definitely finish it in the same time.
