I'm not really sure it's as simple as say a MK2, with the arch being the way it is with the squared off vertical strip (does that make sense?).... You might be best finding THE best person you can and if that means travelling, then so be it. Somone like Greg Howell or Steve Denton.
Unless of course you're just talking taking a few mm off?
Sorry I can't suggest anyone locally who I'd trust.
