I'm pretty sure if you just ask anyone who has ever contributed a driver to the Linux kernel you can find someone who is willing to do "revesing work or special-case driver stuff" for WAY less than $2000/day.

The person who does driver reversing for less than $2k a day is egregiously shortchanging themselves.

Very possibly. And either they're going to take 10x the time (and cost you far more at the end of the day) or they're way underpricing themselves.
