Does he even own a home? Would it cover lawyer fees? Most likely it would be shielded, if he filed for bankruptcy.
I'm not trying to dissuade you. If you can find a willing lawyer, I say go for it. At this point, I would suggest a Florida shareholder lawyer. They would be familiar with Florida corporate law and would be able to tell you if there is a case. With a class action lawsuit, it would probably be a contingency case for them.
A quick investigative check should reveal REDG assets, D&O (Director's and Officer's) insurance, Benny's assets (including his publishing company), and you'll probably want to sue all the board members (probably some money there).
