Any professional and respectable Data Recovery company should have that drive in stock or at least be able to acquire it quickly.
Are you trying to repair the drive yourself?
Physical recovery from that model can be somewhat difficult. If the data recovery center you contacted did not have the drive, I would look for another Data Recovery company. I don't know where you are located, but I have listed a few below:
