Copy Writing (for you tube ad)

Hi! I'm looking for an experienced copy writer to create a script for a YouTube ad. The type of ad I want is an in-stream ad and I have a detailed concept in mind, which I expect the ad to run for 90 seconds. The ad should be creative, engaging, and include all the necessary elements to ensure that it reaches its goals. The freelancer should also be experienced in the specifics of YouTube advertising. This is an important project for us, so we hope to work with someone who will create a top-notch ad for us. Thanks for your interest!
