I don't know of anyone who would do crank bearings just as they were scheduled.

Be very wary of anyone else who says they can locate bearings and rebuild your crank, the parts they are using are almost certainly wrong as the real Koyo parts are not available to retail, as detailed here you'll either get bearings without the locating pin and /or ones not rated to a high enough rev limit.
