There is a list of companies in the first thread of the Mystery Shopping Discussion thread and information on getting started in the New Mystery Shopper area. A good place to start is to sign up at Jobslinger.com (the free site) and see what companies have recently been shopping in your area. The jobs you see are probably gone, but since most clients are shopped on a fairly regular basis (weekly, monthly, quarterly) the jobs you see should show up again, many of them next month.
