PHP Laravel Modification for TMDB Bulk Import

I currently have a PHP Laravel code that uses the TMDB API to import movies, TV series, and episodes one by one. I need it modified to enable bulk importing of these entities.

Ideally, I'd like a developer who has:
- Proficient experience with PHP Laravel
- Prior work with TMDB API
- Capability to blend new code with the existing one without losing its functionality

Scope of Work:
- Modify the existing code to support bulk import of movies, TV series, and episodes
- Ensure the modifications work seamlessly with our pre-existing user interface for bulk import
- Maintain key functions of the current code while integrating new capabilities
