You can also call an appropriate lawyer and let them know where you stand. They may be willing to answer a question or two. I've had good luck with this.
Excellent point. Why pay the lawyer to do the legwork for you? Do the research yourself, but first talk to the lawyer to find out where you should look and what you should be looking for. Asking the right questions is half the battle. Often the 'expert' is the person who knows what questions are the right questions, not the person who (thinks he) knows the answers.
