I have 2 I know of.
One of them is Wheel Recon Enterprise (Ah Tee), I have no experience with him but have heard good things from other members. The other is MPS Auto (Manji), they send it to their contact who does it. I have had 3 sets of wheels done through him that have been of good quality. One was a set of 3 piece rims for my dad's Hilux which were leaking through the bolts. They took care of it and have had no problems since.
