Hi,
I am a hindi writer translator with excellent ratings and experience.
I assume your book will have 75000 to 120000 words in total. A decent quality job will cost you no less than 1250 USD. (here i assume one page will have 250 to 400 words).
Now if you can compromise somewhat on quality, you may get 500 USD bid and if you want excellent quality, It will be approx 2500 USD.
Again, I need to know the subject of the book. Its a story, fiction, science book or something else. It again may impact the bid.
I have tried to pass on the knowledge about the world of translation. AND I hope you like my proposal.
Thanks
