I am writing this cover letter to apply for the post of freelance audio engineer. I know I have the criteria that fulfill your need to complete successful audio projects.
I have been involved with audio and technical work for years as a professional live sound engineer and AV technician. I have the most needed professional certificates in my field, and I possess hands-on skills. I have been employed by theaters, nightclubs, performance venues, and production companies. My resume lists at least a recent company I work with and I can send a listing of hundreds of events I have worked on.
