I also suggest starting with the above advice - the "Most Discussed Companies" is a great way to start. Companies also ALWAYS seem to be looking into the age compliance shops as they don't seem to have enough shoppers under 30 years old. My sons dabbled a little and found that they were super-easy with very short reports and often paid handsomely (at least for mystery shopping).
If you really get into this, you'll find that there are countless varied opportunities in the MS world. (I, for instance, do a lot of new home shops where I spend roughly and hour with a salesperson and my hidden video camera.)
Hard work builds character and homework is good for your soul.
