Ghostwriter for eBook - Lead Generation eBook (Digital Marketing)

I'm currently looking for a ghostwriter for an ebook. The ebook is about lead generation (digital marketing). The book has about 120,000 words, so I was wondering how much would you charge for each 20,000 words.

-The book has already been written, but we want someone to edit it in a Google doc and make it more readable, and add more personality to it so it's more enjoyable to read, as currently we have written the information, and used AI to make it read better and without grammar issues, but we need someone to go through everything and make it better, as the only thing it misses right now is being more engaging.

-Preferably, you should have experience in marketing & advertising books / or the industry in general, so you know what you're writing about, but the information is already given within the book, so as long as you can make it engaging, and worth reading, you could still be a good fit

TO APPLY: Please send your portfolio with links to previous books you've written, CV and a cover also please highlight what service offers within the package (e.g. creating the images within the book; formatting; etc.) can you provide.
