Good garages SW London/Surrey area?

My lady's Kawasaki ZZR250 needs the valve clearances done and unfortunately Doing it myself will not be an option at the moment due to my injury which is really inhibiting my dexterity - not the best handicap when you're faffing with valves.

We live in Leatherhead and she works in Wandsworth, so somewhere around this area/route would be great. Any recommendations for someone who'd do this properly and not rip us off?

Thank you.

Thanks very much for all these, I shall keep them in mind. After a quote (120 quid minimum!) we have decided that we should do it together (she can be my broken hand!) and save the cash.
