If anything a smart step might be the old duster trick. Put a heat gun to the dent until it's hot as hell, flip a can of air duster upside down and blast it. Sometimes the metal will contract and everything will pop back into shape. Though that looks like a tough and strong spot, and I suspect it should be worked from the inside. You COULD try some dent pulling kits, but in my experience they're very easy to make things worse. When the dent is on a radius of any sorts, or contains any shapes within, it becomes a hassle in a hurry. If you want to commit to this, and don't have them already, get some proper autobody hammers/dollies
When it comes to bodywork I highly suggest leaving it to the pros - it's something you and others have to see frequently and if done poorly it's almost worse than having the dent in the first place. "A half-assed job is worse than no work at all." Any place would be more than happy to assess the work and tell you if it can be repaired or to shoot for a new panel, they just tend to vary on price so I recommend getting a few quotes. I've been quoted $350 and $550 for the same job by separate businesses, and ironically almost went with the $550 guy because he was into Toyotas himself and actually knew exactly how to do it right. In the end I suspected he only charged higher because he was a small (but highly rated) local shop whereas the cheaper option was part of a chain and didn't give me the time of day
Or you could always try to salvage one from a pick n pull and get it painted to match, but that probably crossed your mind
