conver my book's word365 file to PDF

I’m looking for someone to convert a book file I have in Word 365 to a PDF. I have specific formatting requirements, and need the file to preserve its original layout. The file is in Word 365, and should be formatted to maintain its integrity and as accurately as possible in the PDF. Experience with converting Word 365 files to PDF is a must.

(1) convert the word file to PDF file and upload the file to Amazon print on demand KDP,

(2) convert the word file to jpeg file requested by some reviewers,

(3)upload the book cover I have in PDF to Amazon KDP.
