Clearerphish, my friend, don't loose hope. Sometimes it just takes a while. With few exceptions, we've had to slog through audition after audition when we've had to get a new bandmate.
On one occaision we brought a guy in without doing any other auditions because he was an ex-bandmate of our bassist. That was a mistake, obviously since he's the drummer we fired.
I sifted through 50 responses to our ads, weeding out ones whose style, genre, personality, schedule, and religion* didn't mesh with ours. (*while not a "church band", we are the official/unofficial rock band for a Unitarian church, on several occaisions this has caused confusion and/or led to me/us being told we were heathens who were going to burn in hell.).
Then of the 5 out of 50 that fit well enough to audition, only 4 of them could actually play.
One was a professional drummer who never understood what I meant with comments like "we practice once per week", "we don't expect to make much money", "most of our shows tend to be charity fund raisers". Etc. But he loved us and wants to be our on-call in case of emergency. He was very very good, but didn't listen to the mp3s I sent and missed a few important changes.
One who came out to audution was fantastic, he fit in almost every way, but he joined another band. He also hadn't listened to the mp3s I emailed and missed spots.
One had a degree in music, but hadn't sat behind a kit in years. And guess what he hadn't listened to either...
We ultimately went with the one who actually listened to the mp3s I emailed him, took notes on the changes, practiced the material, and honestly played the best (not too showoffy, in the pocked, Bonhamesque disregard for drum-head integrity).
Fortunately he's also a good peronality fit.
Not to prattle on about my own band expierience, but I want you to know that sometimes you gotta dig to find that diamond. Put out multiple ads in different places. Heck, our new drummer answered a I posted for "female drummer wanted" when our keyboardist vocalist wondered aloud about an apparent lack of female musicians out there. Our new drummer didn't respond to any of the other ads (he used to be a she), so I'm glad I posted it .
Keep slogging away, Clearerphish, you'll find your bass plucker when the time is right.
