@Hyde,
Welcome to AH
I've imported 2 warthogs and 1 baboon along with several other pieces of taxidermy and haven't had any problems getting my animals into the US.
Since I live East of the Mississippi and roughly an equal distance from Dulles and Atlanta airports and have flown out of and into both airports. I prefer traveling out of Dulles. Flying out of Dulles has been less expensive on Qatar than Qatar and Delta via Atlanta.
Package deals: I figure the number of days I want my trip to be and plan my animals accordingly.
When checking out outfitters I recommend an outfitter that doesn't charge for both your arrival and departure days, only for your hunting days.
Example:
The outfitter I hunt with in the East Cape, RSA offers 7 full hunting days, and doesn't count my arrival or departure days; roughly 7 full days, 2 half days (depending on arrival and departure flight schedules), 8 nights at the lodge. A 9 day total trip.
Some outfitters offer a 7 day trip but you only hunt 5 or 5 1/2 or 5 and 2 half days depending on your arrival and departure flight schedules.
Talk with outfitters, vet them though the forum, ask who has hunted with the particular outfitters, get members opinions and experiences, "The Good, The Bad, and The Ugly."
Figure out your budget: ie
Flights, surcharge for taking weapon(s) or gun rental plus ammunition.
Daily Rates
Trophy Fees
Taxidermy deposit
Tips, if you choose to tip
Souvenir shopping
Snacks, meals, drinks, etc. between flights or while traveling to and from hunting areas or just out and about away from the lodge.
Then discuss with your outfitter what kind of package deal they can offer you. You might be able to add an extra day and/ or another animal.
As previously mentioned TIA expect the unexpected. You'll definitely want to discuss with your outfitter about being able to substitute /exchange animals on your package list for animals on your Animals of Opportunity list. Because you and your PH may see a lot of a species on your list, but not a trophy quality animal.
IMO the easiest Pg trophy size animals to hunt are impala, springbok, blesbok, duiker and giraffe. Warthog depends on the area. The hardest of the PG animals: bushbuck, bushpig, the tiny ten, kudu, eland, gemsbok, lechwe, sable, hartebeest, zebra, and wildebeest.
Good luck with your planning and Happy Hunting.
