Is bitlocker key required for recovery?

[RPT]

Can anyone share conventional hard drive data recovery companies experiences?
My question is based on bitlocker encrypted WD Red 6TB hard drive, which fails to initialize.
Something wrong with read channel or possible track/platter misalignment.

1. When business hard drive is bit locker encrypted, is there any recovery service providers just fixing hard drive without access to encrypted data?
For example changing faulty read head and etc. since business data may be more valuable then leaking recovery.

2. What might be starting price level?
This obviously varies in a very big scale.

1. Sure, the best solution is to receive a healthy clone drive. Low chance you may not be able to decrypt the data on your own.
2. Data recovery prices vary through out the world. So, it depends how faraway you want to send it.
