Blade Dancing Bard

I'm playing in a game set within a third party setting(Aetherial Expanse). I was drawn to the idea of playing one of the subclasses it added, College of the Blade Dancer. We just hit level three and I like the idea of a dual wielding bard, but the lack of extra attack makes me wonder if I should just play as a Valor Bard rather than go with this subclass as I'd intended.

Ideally I want to focus on melee, with spellcasting to support that end. I'd prefer to monoclass, which is supported by the Resonant Blades cantrip, but I'm uncertain of how I should build moving forward. I'd love to hear people's thoughts.

Thanks in advance!
