Need a screenwriter for 246 pg book; history/gullah/action/adventure

We are YBR Publishing, LLC, and many of our clients are looking to turn their books into screenplays. This one in particular is 246 pages; named Driftwood Unmasked; it's a fictional book but the main character is a real person. The book follows the life and times of Driftwood Cory, living in amongst the Gullah folk in the SC Lowcountry after going AWOL from the British military. Lots of action and adventure, and "good ole boy southern law enforcement". The most difficult part of the book is getting around the Gullah language.
