Hi, Mooski,
I know you'll be at work now, but this might help when you get back.
Arranging a courier is easy, but you will need to know from the seller the height, width and depth of the package, and also its weight. He will also need to tell you which days someone will be in to hand the parcel to the courier.
Once you know all this, go to the Parcel 2 Go site (
here) and fill in the form for a quick quote. It will give you lots of options (Hermes is usually the cheapest), so just pick the one you want. You can book the whole thing online, so there's no need to be making phone calls during the day when you're trying to catch up on your kip.
Best of luck and I hope the night stint isn't too gruelling.
Lou
