That web site comes up as expired. What legitimate company would be calling or texting at this hour of the morning, which one poster stated was 5 am. This is probably a check scam. They send you a check for several thousand, tell you to cash it and keep the 500, then wire the rest as a "test" by Western Union, or to buy iTunes cards, or something like that. You send the money and the check bounces, leaving you on the hook for the money and the bank fees. Plus if the check is large enough, there is always the possibility that you could face criminal charges as well.
