At the next event she runs she could call her volunteers “unpaid interns”.
Why can’t they organize it as a Flea Market?
Everyone pays a space fee, sets up and runs their own booth. Only the fee goes to the organizer. Everyone else is running their own business. The organizer uses the fee to pay for space, advertising and their services in keeping it organized.
Just like a Craft Fair.
What am I missing about how this is run?
