Does anybody know places to find art peoples who would do art “for free” as in most of us are making games “not for profit”? I guess I’m just looking for people who want their art to be put in the game for free 
I have been making a game and I’m at a point where I probably need to start integrating some art, because most of the other stuff is pretty much done.
I don’t know of a specific source, but keep in mind you tend to get what you pay for.
You could maybe go to OpenGameArt.org and contact a regular poster there and see if they are interested.
You could check out Fiverr, which isn’t free, but probably is going to be as close to “free” as you are going to get.
Here is there page on illustration: https://www.fiverr.com/categories/graphics-design/digital-illustration/#layout=auto&page=1
Here’s someone doing pixel art specifically.
