Michael Lohan -- I'll Hire a GOOD Lawyer for Lindsay

Michael Lohan is taking the judge in Lindsay Lohan's criminal case to heart ... he agrees Mark Heller is a dummy on the subject of California law ... and he wants to foot the bill for a competent attorney.

Michael tells TMZ ... He's already lined up a California criminal defense lawyer who will take the case and they've already negotiated a fee ... a fee that Michael will pay.

Michael is ballistic over Mark Heller, telling us, "This guy is a loser and will drag her down. I already started to pray to God that Lindsay fires him before it's too late."

Michael adds, "Any professional, respectable, or sure-footed lawyer would never conduct himself in this matter."
