You aren't going to have a case until you have a lawyer. You might try legal aid or another charty law group. Or start saving money for an attorney.

NOTE: The use of the Internet for communications with the firm or this attorney will not establish an attorney-client relationship and messages containing confidential or time-sensitive information should not be sent.
