Good quality is worth paying for! Most of the free ones that you’re talking about are illegal recorded cams, where the models don’t even know they’re being recorded, and definitely won’t have signed release paperwork.
If you’re happy to continue like this, that’s your choice. My vids are all really long, shot from a close angle in detail, with willing participants who have signed the paperwork that allows me to post and sell it.
Hope that helps.
