I need a logo for my new business

I am a conference host, chairperson, expert speaker and public speaking coach. I am establishing a new business called Key Messengers to promote my event hosting and chairing services. In addition, I am offering executive coaching to senior professionals to improve their public speaking, and handling the media. The business will also provide subject matter experts to media outlets as business and subject spokespeople. The logo should utilise calming colours and feel professional although no colours has been chosen, so you have free reign.
