Okay, let’s tackle this. So Diana has a mix of skills in aerospace, manufacturing, and product development. Her experience with Six Sigma and project management is valuable, but not extremely rare. Mechanical engineering is a broad field with many professionals. Location is New Berlin, Wisconsin, which is not a hub for aerospace or manufacturing. Industry demand for mechanical engineers is generally steady, but not extremely high. Considering her skills and location, I estimate her hourly rate to be around $100, which is on the lower end of the scale for mechanical engineers in the US.
