Script Writer for Cinematic Trailer Series

We're looking for an experienced scriptwriter to refine and elevate the concept for a series of cinematic trailers leading up to the launch of 15-35, a youth movement. This isn't a promotional campaign. The objective is to communicate our beliefs, vision, and positioning through compelling storytelling that makes people reflect—not feel like they're being pitched. We already have a rough concept, script, and creative direction. We're looking for someone who can enhance the narrative, sharpen the messaging, improve the emotional impact, and help turn the idea into a powerful film.
