As a former lawyer for over twenty years, my first thought is why hasn't a complaint been filed against your lawyer with the state disciplinary board? Most lawyers have errors and omissions insurance. A finding in your favor in the disciplinary proceeding may require your lawyer to pay restitution. If nothing else, if a disciplinary complaint is filed against your attorney there will be the record of what actually happened should you decide to sue your lawyer. Who knows, his insurer may decide to expedite a settlement.

P.S. -- Since it is against the law to provided legal advice without a license, you certainly should run what I stated by a reputable moneychanger. And, of course, even with moneychnagers, you get what you pay for.
