you going through an outfitter...they should be able to tell you...if not, your taxidermist here can tell you or should be able to..skinning and salting is the cheapest way, if you can skin it yourself, then you pack it in checked bags or ship it to yourself.....then letting a taxidermist out there skin it freeze and ship to you would be next..your taxidermist may or may not take off some for what it cost you to have it skinned...I would 25(read use to)..they aren't hard to skin... about the only thing left you can do is let a taxidermist out there mount it...the shipping will eat you alive though....but its not to bad 120.00 + crating to ship a mounted strutter...the last one I shipped was from here to houston TX...cost to hunter was 120.00 shipping and 80 for me building a wood crate covered in cardboard to ship it in..Look up harry Whitehead in Louisville KY and shoot him a email asking...maybe he will answer you...he is better then Cally Morris IMO when it comes to a turkey. Cally is funnier to watch in seminars but Harry is good at what he does and will spend time trying to help anyone he can...he has a website I can't remember ...google his name and you should find it...
good luck on your hunt
