GSA Rim Damage - Quo Vadis?

Thought I'd ask for some guidance from the forum: During a ride this afternoon, I hit a fair sized rock head on and it left a proper smiley on the rim (see pic below). I obviously need to get it repaired. The bike is insured but I don't know whether this incident (on a district dirt road) will be covered. Any suggestions as to whom in the Joburg area I can take the bike to assess the damage? It was a big hit and I just want to make sure that nothing, apart from the rim, is damaged.

Appreciate your guidance.
