Hello there, Namaste!
I am a writer based in Delhi and I not know Marathi, apologies.
But, the project description was intriguing to say the least. It is seldom that as a writer I get access to real life stories that can be written creatively and be shared with the world. It will be a pleasure and an honour to write and consult on this biography. I can write in Hindi and that can be translated into Marathi with ease. If you feel that some nuances would get lost while translating then I can also suggest a Marathi writer who can work with me in making sure that the essence of the selfless nature of the biography comes out perfectly.
It will best to discuss this over a video call before committing to any price or timeline.
Looking forward,
Kashan
