Shawn,
The Kentucky Ready Mix Concrete Association (or the similar Indiana RMCA) can guide you and should be able to direct you to contractors or owners with ICF experience. They are in the business of promoting the use of concrete and will be motivated to help you. Here are some links to their web information on ICF.
KRMCA ICF InfoIRMCA ICF InfoAlso, check out the Insulating Concrete Form Association at
http://www.forms.org/index.php. Search using the "Find ICF Professionals" section on the left side of the homepage and you'll find ICF contactors in Indiana. I saw two listed contractors that are in southern IN.
In keeping with the food topic here note in the link below that Louisville restaurant August Moon was constructed with ICF. You might call owner and fellow restaurateur Peng Looi and ask him about his building construction and operation. He is registered on this forum as "looi", so you could PM him.
August Moon constructed using ICFAlso, if you work with an architect to design the new place, find one with the LEED certification. The certifcation is trendy now, so you'll have little trouble finding someone. They should be knowledgeable on the ICF subject and can help you find other ways to build a "green" building. If you qualify for the silver, gold or platinum LEEDs credits, you might be eligible for some tax breaks, although the up front construction costs will be higher than costs of conventional construction.
