I have hunted Illinois for over 20 years as a non resident, going through an outfitter was how I got started. Think I did 5-6 guided & semi guided hunts and never killed a deer, however I did see a few dandies' that kept my interest peaked in the area. After that I started leasing ground and have killed one or more deer every year since, including some real good ones.
There might be a few exceptions, but from what I've seen, most IL outfitters don't have huge tracts of land and they pound the pizz out of it sending hunters back into the same locations week after week. 2000 Acres sounds like a lot, but not if you're running ten hunters a week from October thru December. You might get lucky, but you could probably do as well or better hunting on your own. Most of the outfitters also tend to play up their accommodations and meals, and it turns out crummy to average at best. I'll take a motel or camper over many of these so called "lodges".
For the $4,000 you guys will be spending, you could probably lease a small farm and hunt it all weapons, multiple trips and do things the way you want. You also won't be held to some 140" min standard (or fined) like so many outfitters want to push. There are also some pretty good public areas around the state if you want to go cheaper yet, but it will be a bit tougher than a private lease.
