I know someone who imports fairly regularly to the East Cost (her family breeds them, she is Irish). I think $10,000 is a safe estimate for importing costs. Could be a bit more, could be a bit less. But that’s not a bad ballpark. I believe she is still flying them here with no issue, even with COVID.
As for what you’ll pay for the horse-- it’s so variable depending on who you buy from and what you want. Same as here. You can spend $10,000 for a horse or $100,000 for a horse.
Her green ones are something in the ballpark of $30,000-45,000 once they land here. And there’s some markup in there but not TONS because, as I said, these are horses her family bred and not ones that she bought. They’re jumper types with some 3’0 and under show experience, basic dressage, and foxhunting experience when they land here. So I suspect you could get something somewhat similar for maybe $25,000-30,000 all if you bought it right from Ireland.
I do not get the impression that Ireland is the place to get a “deal.” We’ve got had some Czech horses imported and they were ABSOLUTELY below market for what that horse would cost elsewhere. The Irish ones don’t seem that way to me. You can get a nice one, and maybe save a little money, but you’re not going to get one for a price that is WELL below market here. You might get a bit more bang for your buck. This is assuming something going and showing, I don’t know about babies or really greenbroke ones.
