Corporate Conservation Partners with both the IGFA and The Billfish Foundation, plus they do really nice work. If you decide to go with them then please tell them you got your recommendation from this site--I'm sure John and the staff would appreciate it.
I purchased mine through King Sailfish Mounts in Florida. I am absolutely satisfied with the quality of their work. Easy to work with and the price was fair.
