Easier than you imagine, except that you need to go to a "blue collar" bike shop that fixes low and mid end bikes, not to a high end pro shop. Jamis didn't make the crank, they made the bike, or more precisely, had a frame made, and assembled a bunch of standard parts onto it.
You probably won't find an exact match, but will find something functionally equivalent. IF you don't, PM me, I probably have something comparable, but you'll need to either buy a few tools or visit the local shop to have it installed.
As I said earlier, your best bet is a bike co-op where you'll not only find inexpensive parts, but will be shown how to do this job, and others yourself. Otherwise, the next bet is a bike shop specializing in basic bikes and repairs, aka a fixit shop.
