A good start, if you haven't already, is JobSlinger.  It's a free site that will show shops in your area.  From there, you'll sign with MSPs for those shops.  Other suggestions are the scheduling companies, such as Kern.  We have a list of MSPs here, at the top of the Mystery Shopping Company Discussion board of this forum, [
www.mysteryshopforum.com].  There's no shortcut to finding work.  Register with as many as possible, and more.
