I have a great command over both the English and my native tongue, Hindi.
If you have a particular way in which you require the voice-over, I will provide the voice-over accordingly, or else if you require someone to modulate the voice-over, I would be happy to use my creative liberty.
Also, if you let me know the duration of voice-over work required, I would be able to give a better insight for the time required to complete the project.
Do let me know. Thanks!
