K Series fettling in Chesterfield / Derby area?

[stackmonkey]

Sorry for the cross posting (in Midlands area too)
Does anyone know of a garage they can recommend to fettle and reliably modify a 1.8 VVC K series engine?
There's nothing wrong with it at the moment

Friend of mine wants some work done and has been let down by a place in Sheffield.
Anywhere in reasonable travelling distance of Derby / Chesterfield.
No particular rush as he'd rather get the job done right.

Thanks for any suggestion.
