Does anybody have any personal experience with this company?

I found this website, http://www.mail4revenue.com/ It's a company that says they pay $10 per envelope that is stuffed and mailed. On the phone they say the materials that are being stuffed into the envelopes are purchased by consumers for $50 a piece for credit repair and that's how they can afford to pay $10 an envelope. I asked them on the phone how come they didn't have machines stuff the envelopes for a lot cheaper, the answer was that the materials are to thick to be stuffed by a machine or something to that effect. They also guaranteed me on the phone that I would get the registration fee back after three weeks of sending in envelopes or if I choose not to do it anymore. The name of their company is Atlantas Mailing Company and their based in Georgia. I have done a Google search and BBB search and can't find anything about them on the web. I'm looking for anyone that has had any personal experience dealing with this company. I know that most of these are scams and that most people will answer this question just uming the fact that it is a scam but please no negativity unless you have a personal negative experience with this company. Has anybody ever order their products or did any work for them? Please someone give me some facts about them! Thanks a lot!
