Hi there,
If I understood the details right, the book can be in either English or German, and on any subject whatsoever. Is that correct?
If you have any details in mind for the project, please let me know via message. That'll help me provide an accurate quote, and decide whether this is something I'm able to do. The current bid amount would be my fee for roughly 6,000 words - although the subject and the amount of research involved might affect it.
Thanks,
Priya
