$6 to $700. can't be the broker's fees. You have to realize that there are "hidden costs" such as customs single entry bond, USFW fees, duty? (paid on price of taxidermy fees packed), customs examination, local cartage to and from place of examination, inland freight, messenger fees, postage, petties, forms, long distance phone calls, special attendance.
Trust me, I was in the business for 30 years and there have been a lot of changes since 9/11.
Ask the broker for a breakdown of all charges. His fee should be close to $200/250 tops with the rest being out of pocket expenses.
If you live or are close to a USFW inspection facility you're costs and aggrivation go down quite a bit, but there are no guarantees. That's what you pay a broker for. You can't beat experience. Some forwarder's will try and sell you a door to door shipment all inclusive duty paid, delivered. In my experience most are total rip off's.
If you use a broker be sure you get a detailed invoice with all backup invoices as some brokers will mark up other fees to pad their wallet.
Customs or DHS as they are now won't even give you the time of day without a written release from fish and wildlife and usda and you must get a signed carrier's release from the airline or steamship company evidencing right to make entry, then you have to get an inspector to write an informal entry and collect any duties. If all goes well the inspector gives you a release and you go to the pier to get your trophy, but you are denied access to the port because you haven't had a background check so you call a local trucker after you faxed the release from customs and the steamship company along with an inland b/l. Depending on the port, you may have a smooth ride or a bumpy one. Just try to get a real federal govt. employee on the phone unless you have their private number will most likely be a nightmare.
Good luck.
