I am in SoCal, so not exactly central Illinois, but welcome to the Flow Forum!
I understand that you are new to this, but you already know that many traditional beekeepers are suspicious of Flow hives. (This is a forum and I trawl many threads 
) Your insight is a great start.
By way of an introduction, let me say that I have about 30 years of beekeeping experience, and 2 seasons of Flow hive experience. My husband is an avid beekeeper too, and we are both scientific biologists, although not entomologists by training. I still have a mentor myself. Much of my beekeeping has been in a different climate, and with different hives, so his input is helpful.
I would suggest that you try to get a local mentor from a bee club near to you. I would not mention Flow hives at the outset, but say you are setting up an 8-frame Langstroth (if you have a Classic Flow hive). The methods for success are the same with both, it is only the honey extraction which is a little different. If they use 2 brood boxes for over winter (highly likely), you should too. If they insulate their hives, you should too. Etc. You get the picture.
Any questions about general beekeeping or the Flow hive, we have hundreds of people here who are willing to help you. Any questions about local methods, your local club is the best source. 
Not wanting to scare you off, just saying it is good to blend both sets of skills.
All the best for the holidays.
