copywriting company profile

I have started a global agency focused on creating effective global brand partnerships between artists and brands. I need assistance in reviewing my company profile to make it seem more professional. I have 16+ years of senior marketing experience in corporate and have numerous years of experience in brand partnerships . I however haven't done any partnerships yet with my company, so I need to make it sound impactful without any previous work examples. I have already written up the company profile and need assistance in finessing it and reviewing the copy. Knowledge of the music industry would be ideal.
