One of my commercial tenants is a baker.
He gets icing in these big tubs, that seem sturdy.
I would look for something like this since they are food grade, and probably free.
They come complete with icing residue and its associated aroma that some females could find attractive, although females of the species are notorious for their unpredictability.
If the fish gig doesn't work out, you could use the tubs to start plants in. The tubs have handles, so are convenient for carrying the starter plants to the nearest public forest.
