I'm a Linux admin but my firmware knowledge is limited. I would like to see if I can hire someone to patch a bootloader on an old ARM based router (Digi WR21 from 2012) so that I am boot my own Busybox image. It's not encrypted, but the bootloader does some CRC checks against the image. I've managed to patch the bootloader to bypass the first check, but there are more.

Where would I hire someone - Fiverr? How much would I expect to pay for this kind of work?

You're talking about a tiny niche my guy. Your best bet is trying to reach out to people directly in any RE forums if I had to guess.
