If you have the funds and don’t want to mess with emails then use an online service.
If you want an adventure then here is what I’d do. First, have you tried contacting an engineer of the hardware device, if it’s old and depreciated, they might release the Gerber files to you, if you network. It’s harder to do with big commercial products (Apple), but it’s the first step.
Second, search the web if someone has already RE the board; reddit, github, hackaday.io, darkweb has (a lot of apple PCBs), etc.
Next, I would contact YouTube’ers who RE electronics on their channel and ask them if they’d be interested in doing it for monetary compensation, which might be cheaper than chinapcbcopy.com.
Lastly, if the cause is noble, email some university professors who have done similar work, and see if they have a grad student they can throw at it.
What hardware are you trying to RE?
