Forensics Examiner to Examine a Handwritten Signature

Hello, I am looking for someone to examine a signature as fast as possible, not someone to do a detailed research but to tell me is the signature is genuine or a fake one. It is really important to act fast to see if this is a story worth to go to courts or not. I have multiple samples of genuine signatures from the real person and a high analysis sample of the signature to be examined. In case this is not genuine then we will arrange to go through a detailed examination of the document.
