Translation from Hindi / English to Bangla

We need to translate dialogues for training videos from Hindi / English (as the reference language) to Bangla. We will provide the Hindi & English dialogues. We anticipate ~6000 - 7000 words. The training material is targeted at blue-collar workers, but has limited technical details, and is conversational. We will need the artist to sign an NDA with us to ensure compliance before executing the work. Sample dialogue (in English): ============================================ "All of us work at heights and are familiar with the gratings we are standing on, that protect us from a fall. We should never work near an open grating unless it is barricaded. And for safety, we must always use a lifeline. Have you ever wondered how safe the jaali that you are standing on is? Take a look here, for instance. Because this open grating is barricaded, it is safe to work near it. Let us see what can happen when we work next to an open grating that is not barricaded."
