does anybody know where i could buy tin squid molds?

find one you like and make a mold of it- you could make a mold out of RTV silicone or you could use Bondo. If you really wanted to get fancy you could make a rubber mold of one, then make a couple wax copies of the original.. then make another mold around those waxes and send that off to a foundery to have a do-it style mold cast in aluminum... then you would be in business :D
