Where to build around Baton Rouge?

My husband and I want to build within the next 5 years or so but are completely stumped on where to find a piece of land. We don't want to be in a neighborhood, would prefer to find a good 2 acres plot or even more if available and within budget. Where are the best places to look? We would love to stay around south Baton Rouge, somewhere off Nicholson or Rive Road, even in Iberville Parish but on this side of the river would work for us. Can anyone point me in the right direction? This is completely new to us and I am not from here so I don't know where to find land by the acre. We drove around today looking around Bayou Paul in St. Gabriel, some nice houses scattered around but didn't see much for sale in the way of land.
