Anybody know sites where to publish researches for free?

The sites I found requires me to pay them to have my research out-- like I didn't know this?? I don't plan on profiting off a research about literally CSA/CSAM?? It's about how child marriages are somehow legal thru religion/beliefs. Which laws tend to slip by because there's also a law that protects these religions. We actually got done and already bookbind it, I know the process takes like very long like ofc checked by professional and more research defense. Still I don't know where that is for free!! I'm shocked you have to pay LOTS. This research has been ongoing for a year now... Still defending it to just get published.
