As for SM/Orkish objectives, could you use missile pod Bitz, or place a few weapon Bitz on a base? I'm not incredibly versed in what constitutes the typical objective (we tend to use small barrel-and-supply objectives, on a 40mm base). However, having been given a tiny 'lava' lamp keychain for Christmas, I've used it when playing against Eldar, as it looks like something they'd use, haha. They're just miniature lava lamps with glitter in the water, and a color-changing light at the bottom. I saw them for $3.99 in a store here, and you'd probably be able to find them online.
