Thanks answer. I suppose it wouldn't be yes to all of those answers. Although we have a quote work, ultimately the job is hourly paid and is logged on a timesheet signed by the client so can vary from the quote.

The only risk to their own money is that they might not be able to find work every day.
They do regularly work agencies and venues though.
