...and if you don't want to do the restaurants, etc., there are many, many other jobs, with banks, with retail stores, apartments, feed stores, bait shops (heehee - just kidding, but not kidding about the feed store!), etc.
I learned all I could before I started - do a search on your computer for Mystery Shopper Guidelines, that should bring up many learning opportunities. Oh, another good place would be KathyStucker.com. She is a gal who has made a name for herself in the business.
Then, I did what they said to do... I signed up with about 25 Mystery Shopping Companies. I started getting jobs the next day. I was overwhelmed and had to email a few companies and tell them what I did and they totally understood. I've found that if you are honest with the Schedulers, everything will work out (or not).
I wrote up a little bio paragraph about myself (mainly they want you to be professional & honest). Short and to the point. You will learn how to write these and what the companies want to hear by doing your homework.
When I very first started (it's been 1 year this month) I actually thought I knew everything... heaven help me!! What a joke!!
That's it for me, I now must go look at an apartment and then write a 12 page report about it!
... and remember... practice makes perfect. What seemed like a hassle will become second nature.
Good Luck,
Sue
