Advice regarding "skilled labor costs"

[Jeremy Britt]

I will be using my wife's uncle to handle the "skilled labor" portion of my BRRR project. My concern is: he tends to be a little pricy in his quotes, however, the work he performs is top-notch, and he's always bringing new ideas and perspectives to his projects. My question is, What do you think is an acceptable percentage of the total project to offer him, in an effort to keep his labor costs down through out the process of the project.

I understand this may sound as if I'm being cheap, the fact is, yes I am trying to be somewhat frugal with labor costs throughout the project.  The property was purchased correctly, but I feel we should always be looking for way to cut costs without jeopardizing the nature of the project.  Thanks!
