From what I have read, your attorney does nothing more then guide you, and file the complaint under seal. The actual work is done by the Feds. It is only if the Feds don't want to pursue it does your lawyer actually come into play. My only hesitation is that it is for such a small amount, its not like I would be a millions of dollars whistle blower. What I would actually do is get in touch with the federal attorneys in my jurisdiction, they would be better in guiding me.
