Indian Taco Prices

As the title suggests, what’s the going rate these days for an Indian taco at a pow wow (I’m in Canada)? Thinking about setting up a food booth for a few of the local pow wows this summer but not sure what my price point should be. There wasn’t anyone selling any when I went this past summer and I was kinda bummed about it cuz I’ve always loved grabbing one while being on the trail.
