Post frame engineer stamp for arizona

I'm looking to hire a professional with extensive experience in post frame engineering who can help me obtain an engineer stamp for a post frame project in Arizona. The purpose of the engineer stamp is to obtain a building permit, and the project is a medium-sized one of 1,000 to 5,000 square feet. I have rough sketches of the project, but no existing blueprints. The successful Freelancer will need to provide a stamp of approval for the project in order to meet local building regulations. As such, I need to find someone with a strong background in post frame engineering who understands Arizona's post frame requirements and the associated local building codes. Qualified, experienced professionals should apply for this project.
