Event Photography and videography

My Company is covering a Conference in Las Vegas and we need someone who can shoot both video and photo well. Preferably someone who shoots on the Sony mirrorless system. We are booked for 2 days August 20, 21st. I’ll need someone to be comfortable with working alone for the 2nd day. The project consists of corporate style event photography, video B-roll of the event, and various video testimonials from our client’s attendees and sponsors throughout the day.
