Lepsons in Kent have a good name and did my Turbo wheels.
You can also consider The Wheel Specialists (nationwide). The TWS business at Chester is very good.
It is a franchise, so there could be variability in results, but there might be an outlet close to you.
The one wheel will be stripped back, powder coated and then painted and baked in a day - typically arrive at their workshop by 8am and car ready around 4pm -discuss with them your specific needs and if you have any special finish.
