Data recovery service

Does anyone know a company that can recover data from a damaged hard drive?  I've tried hooking the disk up to another computer and running Active Undelete on it, but it doesn't work.  They hard drive has bad sectors.

Also, how much could I expect it to cost to get the service done?

expect to pay no less than $200, but no more than probably a couple thousand.

Now by damaged to you mean just bad sectors, or LOL DROPPED IT?
