Day rate for Contractor Assistant

[Shay Kent]

Hi everyone! 

I have a problem. I don't know how to pay my on-site assistant. Heres the deal. My mom and him help me on the flips. She does attention to detail work and he does as much as he can do, and we hire out contractors to do framing, drywall, painting, electric, plumbing etc. He's real handy for doing finishing work, home depot runs, and assisting the people that we hire. I was giving them a % of our profits, but that's not really working for me anymore. I want to move him into a day rate, but I have NO IDEA what to pay him. Thinking a day = 8 hours. I'm in Denver area. Any advice will really help me. Thanks!
