I was working in events with a little TV, film and video, but now everything is online. I am taking a whole multi-arts festival streaming. Part of the job as a producer is to squeeze every last cent out of anything to sell from a show. A mainstay income of all big shows and tours is merchandising. T-shirts, masks, hoodies, coffee mugs etc. We’re working with a company to develop merch with our designs and organize the online commerce. Have you tried stuff like that? I can offer it as a service if you need it. The image is just a joke kit for fun.
I'm not sure "stuff" is the thing people go to festivals for, or rather spend money on. But I'm not as familiar with "multi-arts" festivals. Can you tell us more about that?
