Production manage a 10 day online zoom event

Spark Festival is Australia's largest event for startups, innovators and entrepreneurs. This year we will be running the festival as an online experience. Pay is capped at $1000 per day The festival will run on the week days between Oct 12 and 23, making 10 days in total. The days are quite long, from about 8am to 8pm. And each day will feature quite a few separate presentations - perhaps up to 15. We plan to deliver these over zoom. Some of the segments may be pre-records, but most of them will be live. There is no studio or event space: all the presenters will simply present from wherever they are, over zoom. I can do all the pre-production, and briefing of presenters and all the rest. But I need someone to help manage production throughout all the days of the event.
