Wow, you are between a rock and a hard place. I know how scary it is when apartment neighbors are complaining. Sounds like you have tried a lot of different things.
I can think of three things I might try before debarking:
1. doggie daycare
2. dog walker mid-day
3. citronella collar
4. Medication to keep her calm for a few days while you are at work.
(Ok - make that 4 things). I had to give my maltese medication when we moved to another state and I received a complaint that he barked all day. Of course, this was due to adjustment issues and after about 3 days on somekind of doggie valium; he was fine.
I wish you could move because your neighbor doesn't sound all that nice! But understand this may not be in the picture for you.
In your shoes - if all else failed; I would probably have to consider the surgery. I'm so sorry you find yourself in this position.
