Good places to find used engines?

Hey y'all, my car's engine finally gave out and I'm trying desperately to find a place to either buy or salvage a new engine. I have a 93 Civic dx and it's currently my only way to make money as I'm doing doordash in between finding a new job. I tried looking at pick n pull already but I'm sceptical any of those engines would work as the cars they're coming out of are nearly spotless, making me worried that I'll be wasting my time putting a second broken engine in my car. I just can't seem to find places to get engines around here so I'm hoping someone can point me in the right direction
