Mag wheel repairs

So the SO fetched me from work on tuesday night and while driving home in the rain, she hit a pot hole on John Vorster. The air is running out slowly, so i re filled it with air and put it in the bathtub filled with water, (had to clean up afterwards cos she k@ked me out) Tyre is still ok, but the rim has a kink on the inside and the rim has a slight crack(you can see the water bubbling when the rim is submerged into water) so i marked it with chalk.

Is there a decent place in centurion that can repair this?
