There have been a few unsatisfied customers report in Don Causey's "The Hunting Report".
The last Hunting Report release suggests they may not even be conducting business anymore. Apparently, 13 hunters booked with Nunami were stranded in Montreal in October. Several other hunters booked with Nunami received calls saying their hunts had been cancelled, but have not received a refund. Causey's organization tried contacting Nunami but have been unsuccessful.
If you have haven't subscribed to "The Hunting Report", I'd suggest doing so for research on outfitters like this.
