Consider adopting a “not my problem” approach to the Florida firm, and find somebody who understands customer service and pompadour windows nearer to Illinois? Not trying to be a smart*ss, but that would be my first move. I bet there are any number of good Canadian firms that would be only too pleased to sell you a couple windows.
If not, see if a local freight consolidator in Florida would include your windows in his next container going to Illinois. What they basically do is fill up containers full of stuff for all sorts of people, then unpack it when it reaches its destination and distribute it to where it is going. Dunno if they do this in the US, but I suspect so.
Giving the Florida firm the business merely reinforces bad behavior. Even if shipping isn’t core to their business, they should at least make some effort to nudge you into the right direction.

Thank you so very much for insights and guidance! Indeed, we do not wish to reward unseemly behavior.
Yes, it is called "LTL" shipping in the U.S. (LTL as in "Less Than a Load" I thought, although it appears that "Less than a Truck Load" is the more common expansion from looking around the web.)
Federal Express does LTL shipping, as do many other companies.
