I've previously used The Wheel Specialist on two occasions (not for my QP yet).
There is one in St Albans if you google them.

Depends what you're after and if there is any damage over and above scuffs you want sorting. I've always gone for a full refurb which involves tyres off the rim, dipped/stripped and completely primed and re powder coated to a finish of your choosing. As part of that process they make good any scuffs or dings. Refit and balance
If you just want the face doing then the tyre can probably stays on.
Normally they'll turn it round in a day if you leave the car with them early - but obviously check first.
Prices depend on rim size and finish you want, assuming no major surgery required you're probably in the £80 - £100 a corner region for a full tyre off strip and re paint. Just the faces - probably a lot less.
