Looking to develop 85 acres in Cincinnati, Oh, and need help.

[Doraine Warner]

It's currently a horse boarding farm, its a gorgeous property, with woods and rolling hills, and pastures. It is a family owned property, and is worth in the millions. It is the largest parcel of land in the city limits of Cincinnati. We are novices at this, and would like to see something from our inheritance. It does has some slippage issues, but it has been built on. How do you go about finding developers for the land? It is a big undertaking. Would appreciate any advice.
