I'm curious if there are marketing professionals who would willingly take on the challenge of promoting my new novel effectively and at what expense.

My latest novel, working title: "The Man Who Refused to Pass Away", delves into contemporary issues, with a philosophical exploration of life's meaning and the intricacies of relationships. It aims to guide readers toward living their best lives in every aspect. Now, the challenge lies in making this book known to thousands of potential readers. Without active promotion, my online writings about the book may go unnoticed. How can I ensure broader visibility for my novel?
