You don't need special contact printing papers. I contact print to graded papers all the time. You can also contact print cyano or coat your own platinum/palladium papers. It's fun and not difficult, and you certainly don't need a darkroom with those- they need quite long exposures with black lights or similar UV sources (or the sun).
Silver paper is quite sensitive and the result depends a lot on well-controlled exposure, but it's still pretty easy. To do silver contacts, all you need is a light source mounted high over the table in a fixture that cuts down on light leakage, and some sort of aperture to cut down the intensity. You can make something out of a simple can and light bulb. You probably want to aim for ~10-20 sec exposures so that you have time to dodge and burn, and so that minor variations in time won't affect your result too much. If you want, you can get a timer and work more precisely. But by varying the distance from your paper to your light source, you will be able to vary the exposure over a very wide range and you can use a simple switch.
Look up Edward Weston's setup. It really doesn't get more simple! Remember, it is meant to be fun.
