Hi, welcome to the forum. I suggest you go to the New Mystery Shopping area and read the first few threads. They contain a lot of information bout how to run your mystery shopping business. Below at the bottom right on this page is a blue link, Official List of Mystery Shopping Companies. These are reliable legitimate companies. You will make online applications with the companies, providing your personal information, SS#, and you may be asked to take tests or give a writing sample. You will be required to sign a confidentiality agreement. After being accepted as a mystery shopper, you will be able to search the company job boards for jobs in your area.
