I worked for a similar company, Lionbridge. It paid well but was somewhat of a pain in the ass. I worked it for a year and made $14.50 an hour. I believe the starting pay is now $13.50 an hour. Lionbridge calls the job Internet Assessor or did up until about a year ago. You have to meet a minimum of 20 hours a week for Lionbridge and usually the maximum is 40 hours.
You can find information on the 3 companies I know that have this type of job, Leapforce, Lionbridge and Butler Hill here: http://www.workplacelikehome.com/
You will have to make an account and then in the forum you can find subforums on the companies.
Be aware that there are a couple of hundred pages of instructions and the test is a BITCH, but it is a good work at home option for those that need to work at home. Expect burnout in about a year. As I said, Leapforce is legitimate but like Lionbridge, can be a PITA at times. But, $13.50 an hour is nothing to sneeze at if you need money and work. As to whether or not it is worth it, that depends on your patience level and your ability to read and follow directions. It's also a good way to get your foot into the work at home work force.
I currently work at home for a couple of other companies writing.
If you decide to go for it and need help, just PM me. I can offer some insight into the guidelines. Leapforce and Lionbridge use the same guidelines and have the same test.
