There’s a market for everything if you know what you’re doing and your work looks good.
Tabletop photography is a different beast; there are photographers that specialize on tabletop photography and video only. Like dhart said, learn that first and then worry about camera movements. Food, glass products, shining objects, jewelries, cosmetics, etc, they all require different lighting and zillions of set-up techniques, you'll also need a lot of little gadgets and props. Standard video lighting and techniques will not get it done.
There are several books and DVDs on the market that can help you, mostly are for still photography but that’s the important stuff, video is an add-on.
Also that slider doesn’t give me much confidence, you would be better off with a plain dolly with PVC pipes that you can also use for other jobs. Also remember that a camera movement is ineffective if you don’t have other objects in the image that show movement and depth in relation of each other, if it’s just a side move might as well use a still photograph and then program all kinds of moves in your editing.
