Contact some of the companies you mystery shop for. If you have a good track record with a company and they need schedulers, it should be easy to get in. I got an editing job with a MSC when another editor suggested me. Unfortunately, after doing it for a while, I didn't like it. Editing was way more work and way less pay per hour than mystery shopping, and I didn't stay around long. A Closer Look just recently had an announcement on their home page that they were looking for schedulers and editors, although I notice the announcement has been removed, so I guess they hired some.
