Looks like this place is trying to get people who meet the new insurance company mandates for being mentor pilots in the new VLJ's and the TBM's and Pilatus. Pretty good money. Sounds like a nice retirement or part time side job. Doesn't seem regular enough otherwise.

jobs page says 6,500 PIC turbine to be a mentor pilot. Less time if you still have valid CFI stuff.
