Here's a neat service I just tried out and it worked well. http://www.borderhq.com/ Might come in handy for other people here too. P ;-)
Hmm, there is a dutch flag on the bottom of the page that should be indicating the service is also available to the Netherlands, but if I try to sign up I can only choose a UK adress.. Strange. Looks like a decent service though, will certainly give it a shot if I can!
