This was my first Airbnb purchase. I used a DCSR loan and I spent around $30,000 ...

Your suggestion is a heads I win, tails you lose.

The best way to win is staying in the game the longest. 

Generally most people you speak with are going to provide you a quote with their "standard" commission built in and anything less would be them taking a reduced commission to win your business. 

Because I rarely have to evict (one every 5-6 years) and because I always win my evictions.

Chances are you won't get anything even if you go to small claims court and win. 

Sounds like an internal policy decision that you will never win, regardless of any reasonably prudent measures you take.

For supercharged cash flow I like this rule of thumb as my #s seem to flesh out well w/in these margins:1BR under $100K2BR under $200K3BR under $300K4BR under $400KMaybe you can go up a notch on each if you want to break even w/cash flow...so to each his own w/that.Of course if they are being sold furnished / turnkey, I'd add in $5-10K of value (depending on how nicely furnished it is) per bedroom.  

Jeff Dilldine’s first fix-and-flip turned out to be a major win, as the home sold for $425,000, delivering an excellent profit.

If they are under paying then I would try to find a win/win where they pay but you handle the vendor relations.
