I have a problem that I wish some of you good people might help me with. And thanks for allowing me on the site

I painted a few years ago and I painted on canvas. I have started up again, but this time I am painting furniture. My first project was a metal filing cabinet and it turned out beautiful. But here's my problem. Canvas is cheap, furniture is not. I just bought a house and the filing cabinet was in the attic, so it didn't cost me anything.
I've tried Craigslist and everything is too expensive. By the time I find something I want to paint, I would already have almost $100 in it! Does anyone have any ideas of where to find cheap wood furniture or metal furniture? I found a filing cabinet like the one I painted today at a used furniture store and they wanted $50 for the beat up thing
I would truly appreciate any help. I have searched the net and have come up with nothing.... Maybe I'm just not looking for the right thing.
And BTW: I use acrylics to paint with

Also, I live in Jackson, TN
Thanks for listening and I'm glad to be here,
