Vans obtained the following quotes: Air freight by Bax Global: $1184.78 (5-7 day transit time) Sea freight by Geo. Bush forwarding: $1281.99 (3-4 week transit) (This charge includes inland transportation from Glasgow to Kinnesswood of $806.49. If you were to collect your kit in Glasgow, the freight charge would be approximately $475.50)
These prices included insurance, but not VAT and any other charges levied by the shipper.
I opted for sea freight with collection from Coatbridge.
