ISO attorney to appeal property taxes

[Ron S.]

Cross-post from Tax/Legal Issues (hope I can do that, I couldn't figure out how to delete that one):

I'm not sure if this is common in KCMO, but here in Chicago, there are many attorneys that will appeal your property taxes and charge you 50%-100% of the first year's savings only if the taxes are lowered.

Do attorneys do something similar in KCMO? If so, does anyone have any recommendations?

Thanks in advance!
