My first thought, regarding price, was around $15 each. I seem to recall a marketing guy I knew years back saying selling price should be about 2.5 times the cost of materials. So if I understood you correctly, you have somewhere between $4 -$5 in materials in each? Does a price like that make it worth your while? I've seen pretty garden decor on Amazon that runs between $20-30. I'd snap one of these up for $15 in a heartbeat. Particularly those first three.
But a lot depends on prices locally. Look around.
