corporate webinar assistance

Hi 

I'm not sure if I am in the right space but it is as good as any.

I'm looking for a freelance Zoom Guru to run a zoom webinar for a corporate blue chip company to it's customers. Not an occasional user for in-house group of colleagues.  Someone with a lot of experience in running slick public facing webinars with a few hundred customers on line. They must have deep understanding of Zoom and be able to handle novice and experienced presenters.

Is there anyone on this channel that can help. Preferably in uk or European time zone but not a must.
