I have done work for a few of the companies listed. The ones that I worked for always paid, and I never had any problems. TES, Byers Choice, Quest for Best, Jancyn, Check Mark, Certified Reports, Best Mark, A&M. Some pay faster than others, but most pay in 30 days after a job is done. Some pay more than others, and some have more frequent jobs than others. Just sign up for as many companies that you can if you want to stay really busy. The more you sign up for, the more likely you are to get a variety of jobs as well. Good luck.
