Have you thought about Ebay???

Or sending flyers to schools, kinders, child care centres etc... rather than spending $$$'s on hiring a hall, maybe offer to come to a school at 4pm on a Friday afternoon to show the stuff you have?
I know Kinders & school sometimes have market nights they charge $10 to have a stall (as a way of earning funds for the school) & different pple come to sell their wares???
