taking pictures at a conference @ Biola University, La Mirada, CA

I need a photographer who will take pictures at a conference. The conference will be held this Saturday (Feb. 25, 2023) 2pm-6pm at Biola University, La Mirada, CA. There will be a series of talks given by different speakers. Total number of speakers is 11, and the size of audience is around 60-70. The job should be relatively easier than baby photos or wedding photos as the main focus is to capture individual speaker's pictures and overall audience; a photographer does not need to raise his/her voice to direct audience.
