Complete Windows Laptop Reset & Reinstall

I'm seeking a professional who can help with a complete reset of my Windows laptop. I do not have the BitLocker Key and it seems to be preventing me from running a typical reset, so I think a type of 'forced' reset is necessary. I do not need to keep any files or data, so a total wipe is necessary. Following the reset, I require the same version of Windows to be reinstalled.

Ideal skills for this project include:
- Proficiency in Windows operating systems
- Experience in system resets and installations
- Strong attention to detail to ensure a complete data wipe

Please provide your estimated timeline for completion and your experience with similar projects. Thank you.
