Just fell on your "Before Voyager", Janeway's Girl, and let me say that it was pretty good. Bravo mon amie! 
Plus, there are so many fanfictions taking place AFTER the return of Voyager on Earth that, for a change, it was interesting to read one* about what could have happened before Janeway takes command of her new vessel... and it give a certain idea of her relationship with Mark, her fiancé -> even if he ended to break up with her in Hunters (s4), what they shared was enough serious to explain why she refused to yield to the advances made by some people.
Anyway, feel free to become inspired again and again!
(* don't get me wrong, I didn't forget Jeri Taylor's Mosaic).
