Have you checked out the ones where you can sort the pieces yourself? I used to scroll past until one let me hide all the abstract stuff and just see portraits. Now I always look for that filter option first.

Went through the exact same thing last year. Took on a few low paying jobs that ended up being total nightmares, constant changes, and late payments. Setting that floor changed everything for me too. Now the clients who contact me are already serious and ready to work. It filters out the difficult people who just want a bargain. I get less work sometimes, but the work I do get is better and actually pays the bills without the stress.

Saw a neighbor get trapped for hours after a botched repair. Just call a pro, the risk isn't worth it.

Guess your old way was basically dust and prayers.

That metal frame thing isn't a trick, it's just a bad feature like @stella_dixon said.
