Seriously? They are not even a legitimate business. They want you to pay for a membership before they assign a job to you and the job never comes. It's a SCAM illegal credit card charging company! AVOID - do NOT sign up. I can't believe people say they have worked for them.
Unless we are talking about 2 different companies. I am talking about the one that sends a job offer via email and offers a decent price for the signing which is close to you and then they need you to sign up to their database and it cost money via credit card.
