Lets start with scams. Yes there are scams that generally send you a check (sometimes in the name of a legitimate mystery shopping company) that basically say this is yours if you send me some. Legitimate offers will never ask you to pay to mystery shop. Check the stickies for more details on the scams.
Legitimate MSPs (Mystery Shopping Companies) - Check a few places. The MSPA (Mystery Shoppers Providers Association is a trade association in which membership almost always signifies legitimacy. Next, the forums - both this one and Volition.com - offer a wealth of opinions and experiences by shoppers about MSPs. For this purpose I prefer volition to this forum because there all the posts about each company are organized in one thread. This forum is more free-flowing with more targeted threads. Lastly, the BBB can provide some information about individual MSPs.
What are the top companies? I suppose that is a lot like asking what are the best restaurants in your town. Preferences and opinions are a big part of that - but the forums have threads asking similar questions. I suggest you peruse those. What I look for are MSPs that are responsive, well paying, and quick paying.
How to hook up with MSPs that offer shops in your town? Start with Market Force and Corporate Research International. They are both very large with many shops in just about every part of the country. You easily could be doing shops for them in the next 24 hours. After that, sign up for jobslinger (the free version), shopper emails from MSPA, and sign up with more MSPs.
What MSPs shop which clients? You won't get much in way of a response because it would violate my shopper ICA (Independent Contractor Agreement) to tell you which MSP shopped McDonald's, for example. The ICA contains many things we are not to reveal. However, this is the big one to avoid doing. With that said, some MSPs will list clients on their web page.
One more answer - The best way to get your feet wet is to DO SOME SHOPS! Go to Market Force and/or Corporate Research International and get some shops under your belt to see how you like it. Make your rookie mistakes (we all have them) with the rookie type of MSPs so it doesn't harm your reputation with some of the better paying, more desirable MSPs.
Lastly, don't forget to keep the documentation for tax time!
Good luck!
