Powerbook Hard Drive Data Recovery

A few months back, I bumped the desk that my Powerbook was on pretty hard. The laptop did a bounce, the desktop locked up, and that was it. Whenever I attempt to boot up the drive, it makes god-awful sounds, and the farthest I get is the grey Apple logo - no spinning wheel. Sometimes just a blank grey screen. Seems pretty clear that it's a physical problem, as if the hard drive can't spin. I have no idea what this means for the data - if it could possibly still be in tact and retrievable (no, I don't have it backed up, and yes, I know that's a no-no).

I tried hooking up the Powerbook to my desktop in Firewire target disk mode, but the screen just stayed black after powering on. I tried booting from my DiskWarrior 3.0.3 CD, but it will not look at the hard drive, because it's the boot up drive.

The prospect of a home remedy looks pretty hopeless at this point, but if you know of anything else I can try, please let me know. And if not, I'd appreciate it if you could point me in the direction of a reliable, affordable service company that might be able to assist. Many thanks.
