Your best bet in order to get ADMISSIBLE evidence is to find out where he is employed and subpoena his wage information from them. You can try to get him to admit it based upon the social media post, but it may not be admissible, or if admissible, not trustworthy (it's not a statement under oath, as his court testimony is).
