You can rent a crusher & press at your LHBS, if you are close enough to one. Rental is pretty cheap at mine.
You can make a scratter to shred the apples using a number of different methods, including using a food processor, blender, or -- the best trick I've seen -- a re-purposed garbage disposal. Type "scratter" into your search engine of choice.
I have a buddy that used to put his apples in a garbage can and drop a sledge hammer on top of them -- over and over and over -- to mash things up. The riper the better (without being spoiled) he says. Sounds like a TON of work to me, but ultimately effective.
In the end, you're going to want to press the juice out of the mash. There are various methods for improvising one of those too, including using hydraulic jacks and clamps. Easiest press I've seen is made from two 5 gal. buckets. Drill holes in the bottom and low on the sides of one bucket to drain out juice. Fill the "holey" bucket with pulp and place in a pan to catch juice. Set the other bucket inside the first on top of the pulp and fill it with water to act as a press.
