Which procedure would help correct breathing issues caused by a deviated septum / collapsed nasal valve on my left? (photos)

I'm pretty sure I have a collapsed nasal valve but I would like an expert to verify. My left nostril appears larger on the outside but looks almost like a coin slot on the inside. I have little to no issue breathing out of the right side but can barely breathe at all through the left. And the cartilage is very weak. What procedures are there to fix this kind of issue?
