Ghostwriter wanted for fantasy fiction novel

I have a fantasy fiction novel that I have been working on for the last ten years and I am still creating more material for it. This is a novel that is based off of “Lord of the Rings” and “Harry Potter” series. This will be the first book in the series and I do not know how many books in this series I will want. I would like for this book to be 180,000 words, but I am always up for change, if need be.The world that I have created is set up to be used for more than one series. So, if we did ten books for this series using the world that I have created. Then I would be able to use the same world for a prequel or a sequel. It is about four kids who are brought together, because they are Elementals. Two boys and two girls: Main character- Christopher WildFire (fire element, Sarah Clearwater (water element), Brock Boulderdash (metal element) Amari Evergreen (life element). This will be a series that have Elementals, Mystics, witches, warlocks, ghosts, ghouls, goblins, werewolves, vampires, trolls, dwarves, mermaids, sirens, elves, and humans. I do have the first book outlined, but I am always up to change. This will be an adventure that will create memories for all ages for years, if not longer. I have truly put my heart and soul into creating this series. I have mapped out the first three-four books (but only outlined parts of the first book completely), but rest assured, this will be epic. I would like to have a ghostwriter who can write suspense, cliffhangers, action. A ghostwriter to can write a page turning book. This will be for a long-term project, which means that this is only the first in many ghostwriting projects I have. If you have any questions, comments, or concerns, please message me and I will get back to you as soon as I can. I will pay the ghostwriter chosen for this project in installments.
Below is the link to the outline that I have done so far for the first book. It is not finished, which means that I would need the chosen ghostwriter help for finishing this. As I stated before, I am always up for changes as well.
