How much do you think it would cost?
It depends on the lawyer. And Avvo has rules that disallows lawyers from overtly recruiting clients via this website, so none should engage in that type of conversation with you on here.
Your best bet is to contact lawyers individually (not on this public forum's board) if you may be interested in that lawyer's services. Some lawyers charge for their initial consultations, while others do not, like me and several others that I know. I recommend that you contact a lawyer who will give you a free consultation. After the consultation, the lawyer should be able to give you a fee that her or she would accept to represent you.
