Locally, there is a slow, steady stream of 10-12ft corrugated metal at about $10/ea. Random pinholes from it's life as roofing.
One can get Hollywood style bed frames at the same store, IIRC about $12. Those could be cut up for the corners. Driven into the ground.
Instead of expensive nuts and bolts and tedious hole drilling -- a homemade spot welder?
