I do not know a ton about log cabins and kits. I do know that there is alot more involved than a retail or kit salesman will lead you to believe (Wiring, finishing, windows, doors, logs, how the logs are cut, etc). I read that you can have a "shell" done for around $40 sq ft (from foundation to roof shingles,mid grade windows,nothing fancy). But like I said there is lots more to it than that.
I also sent you a link.
