Construction/Remodeling helper needed

I am doing construction on my warehouse and remodeling 600 square feet so I need a part time worker for the next 3-6 months that can lead and help with each part of the process. Things we're doing:

-Adding 300 square feet of concrete foundation with rebar

- Installing a new bathroom and trenching 50 feet for the installation of a new water line

- Framing and building a new 300 square feet room. Tearing out an existing room and adding insulation and drywalling and painting. We also have multiple fences, a storage container, and part of a house that needs a new coat of paint

- Designing and adding a new bathroom with a shower

- Adding new subflooring and flooring and installing 2 heat pumps

- Adding 3 walls

I'm looking for someone with construction experience that can lead these sort of jobs. We'll hire a professional for a few steps such as electrical, plumping, septic but I'd like to find someone who knows how to do the rest of this project safely and up to code

I'll pay 25-30 dollars an hour cash depending on work ethic and experience
