Screenwriter Needed for Adaptation

I'm seeking a certified screenwriter to adapt my book into a feature film screenplay (90-120 minutes). The adaptation should be moderately faithful to the original, allowing for some creative changes.

Ideal Skills and Experience:
- Certification in screenwriting
- Experience with film screenplays, especially in drama, sci-fi, or thriller genres
- Ability to transform narrative while retaining core themes
- Strong collaboration and communication skills

Please provide samples of previous work and a brief outline of your adaptation approach.
