Lens repair or new lens

[Spavo]

I've had a bit of an accident with my favourite Canon EF 17-40mm and it's broken along the barrel at the bottom of the lens and when connected to the camera it is not sitting at 90 degrees, the lens is still working but soft on focus, Wondering a few things is their a good place to get this repaired it's physically damaged so not sure if it could be repaired attached a photo below has any one had something simular and sucessfully got it fixed.

The 2nd Question and recomendations of a replacement lens, will be used mainly on a Canon 5DS R
