Hi Gaz.
Just a few sites I normally use for international shipping.
http://www.transglobalexpress.co.uk
https://www.parcel2go.com
https://www.parcelmonkey.co.uk
Pop the package dimensions into this sites and see who comes back with the best price. Packages will then typically ship with UPS or FedEx. Most wil require you to be available for the item to be collected from your address.
