"I manage to hit level 17 and screamed back to FV to train dual wield.
After a bit of looking around I asked if there was a bard trainer."

Unless it's changed, we bards do not have to train Dual Wield. Once you hit
17, just zone or relog, and you'll be able to wield both weapons. Your
initial skill will be 34.

Of course, it's been a long time, so this may have changed.
