Dump trailer for personal use?

First time i used one of these trailers was after a bunch of trees on my property got scorched from the neighbours garage fire. 19 huge loads of brush/roots to the dump.
I had to have one after that.
Cheapest pos i found was 2 grand. Then i remembered the crusty one someone had mentioned.
500 wouldnt buy a set of good axles/springs.
1/2 the summer building it.
