Where to get stock rim replacement?

So today I was rippin through some pretty deep rocky mud when my rear tire popped, turns out the tire didn’t tear and the bead didn’t break. A rock or something punctured a hole right through my rim, I don’t know if it got wedged in between the calipers and rim or not. Long story short my rim is trashed. I’d like to find a replacement formthe one rim if affordable. If not I’ll just grab a new set, anyone out there that can point me in the right direction? Thanks
