I dont know, but if it is only a few boxes I would imagine you would be paying a lot to a removal company. However, if you used Royal Mail or DHL basically any courier service you might find them cheaper but still providing a fast service.
Have a look in the Irish Post newspaper - used to be several removal companies advertised there. Many will wait till they have a truck full before delivery - i hadn't a huge amount so waited about 6 weeks but all arrived safe and well.
