Need Help with figuring out what to make....

I don’t know if this belongs on the modeling section but…
I’m having a hard time figuring out what I wanna make, I’m looking to make some quick cash, but i’m having a hard time figuring out what I should make, or what sells best.
I’m mainly looking to make things like props, not so much on vehicles and super high poly stuff…
I’m really only looking to make like $30 at most… I guess.

IMO best bet are some figurines, toys, jewelry or decor stuff for shapeways & other 3D print market places…
