Can Ghostwriters Do Anything?

I have an adventure novel idea in my mind that I want to convert into the book. This is one of the ideas that I think is just amazing and it needs to go big. But with the lack of writing skills I will have to start looking for ghostwriters who can help me out in using the best words to be used. Professional ghostwriters can make this idea more amazing and thus if someone has any idea about the ghostwriting company, please recommend me. Also, what are the ongoing cost of such writers?
