Hit by a car, rear wheel buckled

Earlier today some scrote in a golf hit my rear wheel side on at a roundabout therefore it is buckled but still rideable. It's a Mavic SUP XP30 (if that helps), where's the best place to go and get it sorted? Any idea of the cost? I live in Stoke Newington if this helps.

No idea about cost, but you could go to Bike Mech at The Castle Climbing Centre--gets good feedback from people who've had repairs done there. PUSH Cycles in Newington Green is a new bike shop run by very nice people. Two Wheels Good in Church Street is a longer-established bike shop. If you can wait for a bit, you can also go to the Hackney Bike Workshop.

Here's a list of Hackney bike shops:
