Just saw a job on craigslist for a camera op, it is only £80 for the job, but the point is this same job was up there about a month ago and the pay was nothing back then.
So they haven't found anyone willing to work for nothing and hey presto! They're offering money now, hold out people, the only way to stop people trying to take advantage is to ignore all the 'jobs' whereby, travel expenses and exposure is the pay.
If you ignore them, they will pay
