TREATMENTS:
Create a template for your treatments to help make it easier each time you are asked to create one. Your template would have sections like location, lighting, casting/talent, wardrobe, etc. I also suggest hiring a writer for each one and hiring a designer to create the template.
The treatment can make or break it for you when bidding on a job.
I personally think your portfolio should be enough to get you the job, but nowadays why not do everything you can to make that happen? Use this as a way to demonstrate your approach to this project and the type of professionalism, creativity, and enthusiasm you’ll be bringing to the job.
