Drop me a PM with details, how quick do you need it brought down, what's the access like at both addresses, is it drivable usual sort of stuff. May be able to find a competitive rate for you if one of our vehicles is returning that way.

The guy who bought my Porsche used a company called flyingbluedog. He seemed a good bloke, moves some expensive stuff around and is well recommended on the Porsche forums. No idea on prices, but he does have a website...
I can't see that its going to be that cheap as the pick up location is so far away and most people would charge you the total miles covered including getting to Ayrshire in the first place, as David asked how soon does it need doing as I might be able to help but based on fuel and time (not possible in a day) you are still going to be looking at around the £600 mark.
All the companies I would normally use if I cannot collect buses are based down south so its even further for them to travel in the first place.
