Tim, a mate of mine has just bought a tilt-tray. Dunno whether he's up for a big job like that, or what he'd charge, but he's one of the most careful and reliable blokes I know (sometimes to a fault...).
I lost his number in the phone in the washing machine incident of 2012, but his name is Simon Leigh and you'll be able to find him through FaceBook.
I you can't dig him out that way, gimme a yell and I'll find a number for you.
