Wedding at the Narnia Estate?

I'm getting married in three years and I was wondering if anyone knew the cost for a Saturday wedding (200 people) at the Narnia Estate in Lemont, IL? I'm planning on meeting with the coordinators there but before I go, I wanted to have an estimate as to what price range I'm looking at. I know it's pricey but I don't want to be too overwhelmed when I meet with the consultant there and here the price.
