That's a great idea, Danillo, but the problem is that we differ in our choices of the best 3-5 companies. A couple of my favorites are not very popular with other shoppers, and some of the companies I don't work for are very popular. We all have different likes and dislikes. In addition, many companies have different clients in different parts of the country. A great company that I do a lot of work with may have no significant client in your part of the country and vice versa. Also, although I am signed up with about 150 or so companies, I usually work with no more than 20 or 30 in any month....because the jobs tend to come and go. It's a better idea to go to the list on this forum, [
www.mysteryshopforum.com], and sign up with as many as possible. Then, before accepting a job with one, check it out by doing a search for the company on the forum to be sure it has not gotten terrible reviews.
