At one point following the shooting, Zimmerman had his own website and raised $200,000 for his legal defense. His family and attorneys also have set up separate fundraising websites, but it's unclear how much they have raised.
Zimmerman's attorneys say that their client hasn't worked since the shooting. Of course, people in high-profile cases sometimes win lucrative deals to write books or sell their life stories so they can be made into a movie or television program.
Bernstein said if Zimmerman was his client, he would advise against this right now.
"If he's doing a book deal, he should keep it quiet, and don't come out with a book in a hurry," said Bernstein, adding that he would advise Zimmerman not to speak to the news media in either paid or unpaid appearances.
"The more you talk, the more you are a target," he said. "The court has spoken for him. The best thing he could possibly do is go below the radar."
There's also the possibility of further legal action against Zimmerman — some of which could impact any money that he makes.
Martin's family could sue Zimmerman in civil court, much like Ronald Goldman's family did with OJ Simpson. Any proceeds Zimmerman makes from a book or movie deal could be turned over to the Martins, if a civil jury were to find him guilty.
And then there is the possibility that the Department of Justice could bring a federal hate-crime charge against Zimmerman. While legal experts say this is unlikely, Zimmerman could be forced into paying for more lawyers if it does happen.
Veteran publicist Glen Selig said in the coming weeks and months, Zimmerman should let others speak for him and avoid most, if not all, publicity. By speaking to the news media about the case, Zimmerman risks making the story about him — and not about the larger, more complicated issues of race and justice.
"I would clearly advise him not to become the lightning rod for this issue," Selig said.
Emotions over the case are running high, especially among those who think Zimmerman should have been found guilty, said Scott Sundby, a law professor at the University of Miami.
"The hard thing about the law sometimes is that we can have intuitive responses that an outcome is not fair but that doesn't necessarily mean that the law was not followed," Sundby said.
"The criminal justice system is often an imperfect system of handling wrongs that occurred. Many acts we feel were unjust will go unpunished by the law because of larger issues as to why the system is set up that way."
