I got the same thing...let's just say they are frauds and dont cash the checks...

Received an email for secret shoppers I replied and they sent me a $4,950.00 cashiers check. This is the number they gave me.

I got not 1 but 2 calls for a Customer Service Evaluator position with Unique Staffing Marketing Solutions. The number given was 1-888-664-8870 X1, but when I tried to call it I got a recording that the number was not in service.  I also got a $4,950.00 check. I could not find Unique Staffing Marketing Solutions when I Googled it or anything close to it.
