Anyone ever heard of Cornerstone America?

[MF-DIF]

I received a job oppurtunity via email from them to sell finacial services. Never heard of them before. They claim to provide qualified leads from direct customer inquiries. I sell TV advertising don't really see the payoff in what im doing currently so im always on the look out. Id like to find out if they are a well structured established company and not some shady organization.
