I have a cousin that does the same, travels 6 months of the year and works over time, and then take 6 months off, and just surfs and spearfishes. He makes more in 6 months that most do in a year, granted he is working 60-80 hrs a week, but there is more work than there are hands to do it, and all of it pays time and a half after 40 hours.
