Wish I could find someone nearby that cheap! I wouldn't mind doing a class or two with Coach, but 3hrs both ways is wy to long a drive for me, and it seems not many in NWI advertise their trainging offered, or if they do it's expensive (like the instructor Rhino linked me to). It's probably worth the extra money, but that doesn't mean anything if there is no extra money on hand. Hopefully, given the time, I will be able to work something out and figure out how to get some training! The good folks here on ingo seem ready to help, ATM I have neither the funds nor the time, but I will this summer hopefully!
Since you are in NWI, check out the options available across the border in Illinois. I am from Chicago, so I look at schools in Illinois, Indiana and southern Wisconsin. I was willing to drive 3 hours for shotgun training because those courses are pretty rare. If you are willing to drive an hour or 2 into Illinois some more options may open up for you.
Keep in mind that even a single day worth of defensive firearms training is VERY worthwhile. The 6 hour shotgun course took me from a person who had NEVER fired a shotgun before and didn't have the confidence to use it in a defensive situation, to a person who can run a shotgun with ease and now uses it as a primary home defense tool.
