Many lawyers work on a contingency basis - that is, they don't collect any payment unless you win the case, and then they take a percentage of the payment you collect. This can be a pretty big percent, but since you don't have to pay unless you win, it's pretty cost-friendly. You should use your phone book or online yellow pages to find laywers in your local area, and see if you can find any willing to take your case.
You don't have a case but if you proceed;
attorneys who take cases on contingency do so for their fees, they charge for all expenses win or lose. Attorneys never work for free they just get pad less if they lose, do not make the mistake of thinking an attorney who works on contingency is not going to charge you anything at all because that is not how it works.
