If you're flying the plane with your good content, why not have a co-pilot to run the process? You'll free yourself up to attend to the content and not worry about all the back-end stuff that Zoom (or whatever your platform is) requires.
Being online is its own special challenge. I can assist you in:
Planning for success in your next webinar, meeting or workshop
Producing materials and communications for your participants
Supporting the online process during the session
Taking notes so you do even better next time
Try having me as your "Zoom Producer" for your next important engagement!
