Pick up a cheap guitar tuner and tune them yourself. Just make sure it's a chromatic tuner (which means it covers the full range of tones with all sharps and flats and is not just for guitar notes: EADGBE). Also, ensure that you can adjust the calibration up and down from 440 beats per second (standard "A" tone). This will allow you to fine tune / adjust it for the slight tuning variances with the existing chime bars (they all might be equally slightly sharp or flat from "perfect" pitch) .

I've never tried tuning a set, but it'd be an interesting evening at the bench with a grinder, file and tuner. Not sure what note intervals they should be tuned to, but you could check your Bucanneer for a reference.
