Try looking up fishing nets and rigging around you - we called a place and scored > 600' of netting (8' tall, 5'' mesh, I think) for ~$120, which was amazing. They just had in stashed because the size wasn't quite right (and it was bright pink, haha). Anyway, they have awesome stuff lying around sometimes, at a fraction of the cost. Of course, have to ask for mis-specified or marked-down items.
