Need Video Script for 60-90s Commercial/Advertisement (Fitness)

Seeking a script for a commercial that will be showing how to use a fitness app. Need a creative writer who is able to capture the attention of the audience and deliver a memorable message. It'll be a spoken word commercial so there will be a voiceover. None of the actors in the commercial will talk. Will discuss further details with main ideas I want mentioned in the script.

Need a capable copywriter/scriptwriter for this project.
