What do you have in mind for the style and theme of the business card?
My website is currently under construction, but there is a landing page that you could use as a reference. The new website is being designed with a look and feel that is similar to "masterclass". That website is http://www.masterclass.com .
Please feel free to use the microphone in the logo separately from the name in the logo. I have included one of my pr pictures, but am not 100% certain if this is something on want on the card. Will be looking forward to your designs. Also, have an image in my head of a large crowd watching a speaker perform that might be an interesting element, but will let the designers choose their own creative directions.
