I have done over 500 shops. Hotels, restaurants, fast food, grocery store, gas station and some stores. All great companies so far except lately with Gap Buster, problem getting paid.
Market Force, SQM, Frontline Focus, Second-to-none, Shop4intouchshopper All have been great.
In my beginning I had a couple shops rejected but it was my inexperience and not following all the details. Don't work for that company anymore.
I just do it part time.
