Hello. I understand the requirements of this project and I am interested to work on it.
I'm thinking a Word/PDF document with highlights from each book should be ok. Or separate documents if you prefer but I think a single one with with bookmarks for each book would be better.
I am a reliable and hard working freelancer, focused on quality and accuracy.
I will also do my best to finish the work within the specified time frame.
Kindly consider my proposal. Thank you.
