Where to find large off market properties?

I am searching for properties in Ohio, Western Pa, and parts of Indiana but I can't find anything worth buying. Ive picked one property up in the last year and a half but that is with through research and searching for properties almost everyday via loop net and brokers websites, i.e. CBRE and Marcus and Millchap. My budget is 2-8 million. If someone could please help me it would be very much appreciated.
