Dyn-o-mite -- Nowadays I hire a couple guys I know to do the really tough work I can no longer do myself. Or you could consider getting someone with a Bobcat to bust up the caliche -- I know a couple guys who have them up this way.
When I was young and didn't have a bad back or bad hip or shoulder, lo those 25 years ago, I actually double-dug the whole damn huge garden (about 55 feet x 35 ft) by myself, for the most part. Excavated (in sections) to the caliche level, filled them with water and a bunch of gypsum and sulphur and vinegar and let it soak through, refilled with water again, let it soak and then dry out for a day or so, and went down another 8-12 inches and broke it into small chunks. Mixed in a half-ton of medium-fine pine bark with that, then refilled the soil with a couple dozen cubic yards of topsoil-compost-sand mixed in, to make 10" raised beds. Maybe twice in the last 25 years I've taken the time to dig down as far as I could to penetrate any newly forming hardpan, but never have developed that kind of cement-like base again.
I have friends in town who built a 2 foot-deep raised bed -- edged like a redwood bench you can sit on --all around the edge of their back yard about 6-7 feet wide, and filled it with topsoil and compost. Worked great for them.
