The Pat Henry company recently sent me an e-mail needing these done in Walmart and Sam's club. They took several hours and were to be done late at night or early in the morning. They paid well $75-125 for several hours work but there was absolutely no explanation of what work was to be done. It turns out I wouldn't have qualified because you needed a smart phone to send photo's and reports from the site as the audit was taking place. Anyway does anyone have any idea what these audit are all about?
