Googling "everest base camp trek" will dig up all sorts of information. There are several adventure travel companies that offer treks of this sort - typically you'll go in a group of around 10 other travelers plus your local guides. If you're on a tight budget, flying into Kathmandu and booking the trip yourself with a local company can be much cheaper, it'll just require a bit more effort. Depending on the time of year you go, it can either be busy with many other trekking/mountaineering groups, or it could just be yourselves. You don't need to be superhuman to finish the trek, but you do need determination and a relatively good level of fitness.

One drawback with booking a set itinerary is that if your body doesn't take to the altitude well and you need more time to acclimatize, it could jeopardize your trip. Within a group of 10, a couple people likely will not make it all of the way to base camp and will need to stop. If that worries you, finding a more flexible itinerary will let you travel at a slower pace if need be.

This is the sort of scenery you can expect: http://www.youtube.com/watch?v=j6ZPYwlj4bc
