Need Lawyer in Brookfield, IL, Prop tax assessment/reclassify

I think I have found a pretty great deal for some multifamily properties. There are three duplexes that are currently classified as townhomes. In this classification, each unit is taxed individually, however, if they are able to be reclassified, I could potentially reduce the taxes substantially, making them incredible cash-flow properties. 

Would any real estate attorneys who practice in Illinois and have a background in tax assessment and reclassifying property types be able to shed some light on this area for me? I believe there is a lot of potential here.
