External Hard Drive Assistance Needed

I have an external hard drive that is currently not reading on a Windows computer. A specialist has confirmed they can transfer the data off the drive, but I'm unable to access it. The hard drive also has a Bitlocker key on it and I don't have the key. I'm seeking a professional who can help me bypass the Bitlocker key and retrieve my data.

Skills and experience ideally suited for this project:
- Proficiency in working with Windows computers
- Expertise in data recovery and hard drive troubleshooting
- Experience with Bitlocker and bypassing encryption
- Familiarity with various data recovery tools
- Strong problem-solving skills
