Buckled Wheel Repair Recommendations in North London Pls?

I have an alloy wheel with a very small dent/buckle after hitting a pot hole, so it's no longer perfectly round. Just needs a little straightening.

Does anyone know of a reasonably priced repairer in North London? All the ones I know only do cosmetic repairs and not structural repairs. Thanks

Have repaired 2 buckled alloy wheels for me in the past. They weren't cracked. approx £30 a wheel I paid a few years ago. Excellent service.
