You wanna be careful who you quote
, FedEx don't do Northern Ireland, because they are international Only they class Northern Ireland as UK as well.
Get someone who uses Business Post or Amtrak and you are gonna be ok, I know overclock used to use BP and I know overclockers do use Amtrak, might be a wise move to ask Kustom PC's
www.kustompcs.co.uk as they have fantastic service
and they might just be able to give you what you want.....
