Watchoutbelow,
I don't know where you live/work. In the UK, helicopter instructors make £30-£60 per hour, dpending on the school and area. Yes, you may only work for about three or four hours a day on average, it's true. That's around £120/day. Toilet cleaners are on minimum wage - around £4 per hour. Most work about a 35 hour week; that's £140. I rest my case.
