I need a publicist marketing person

Hi I have just completed my first kids book named "Carlos the Concrete truck" I have a concreting business and have decided to write a kids book, as ive noticed how much little kids love concrete trucks and tradies in general! Do you think there are any PR people or publicists who could help me market the launch of the book, I am The concreter who wrote a kids book dedicated to his Daughter Carlos the Concrete Truck!

Thanks :0
