Convert an e-book to a pdf

Do you have any experience in converting a Kindle e-book to a pdf. It's for my own book https://www.routledge.com/Teaching-and-Researching-Listening/Rost/p/book/9781032487908, so it's not a copyright issue--though there may be some difficulty in navigating through Kindle? Of course, I have pre-final versions of all the chapters (before final corrections), but I'd like to convert it all into a single pdf, including the cover. Can you help with that? There are directions on how to do this online, but I figure if someone has more technical skills, they could do it more efficiently. I would pay you in advance for purchase of the e-book, and then pay you the fee for the conversion after I receive it. Thank you for considering this. Please let me know if you have successful experience with type of conversion, with a sample if available.
