100K or 500K, all depends on the finishes. Or impossible to tell from here without a lot more info.

Ask the persons that will potentially build it. Or, add a 75% contingency to Mill's estimate

My house is coming in at $196/sq ft. But that really won't help anyone else. A lot depends on your location, how your lot is situated, do you need a long drive, a retaining wall etc. What you chose for materials inside. Check with a local builder you may find that having one custom built is better than going with an online company.

"My house is coming in at $196/sq ft. But that really won't help anyone else."

Especially since he is only looking for roofing and interior finishes. The shell is done by the log cabin company.

To get some idea I suppose you could take $196/sq. ft. x sq. ft. and deduct the cost of the foundation and shell.

There are way more challenges with a log shell. for example, electricians will have to bore through the logs to fish wire. Also cabinetry may have to be very custom, because you can't just hang a box off a curved surface and expect good results. My dad has a log cabin and while the shell was very reasonable, the finishing took forever and was very costly because so much had to be custom.

Some log cabin designs settle over time, so features to account for that settling have to be built in. Those features are determined by several factors, like what kind of interior finishing(none/sheet rock/paneling/etc.) is planned.

As noted, electrical wiring is way different, codes for plumbing/wiring vary from jurisdiction to jurisdiction, and getting trades people familiar with working on log cabins may be difficult or expensive.

None of the costs can be figured by just any company/trades person unless they know the layout, the requirements and have that experience.

Figure 2-4x the cost of the shell, and you will be in a ballpark in the USA. Without more details, that ballpark could be Wrigley Field, or it could be the Podunk Sand Crab's grassless back lot.

I'm currently finishing up my log home construction. The thing is, area prices WILL vary. And perhaps what the log supplier company provides. Mine has provided the logs, the roof, the subfloor, the porch, windows, two of my exterior doors (I opted to upgrade the others), and the drafting work needed to adapt one of their plans to my needs. They were not responsible for any of the log staining, but pointed me at two reputable companies to choose from. My build is 2100 square feet.

Anyhow, it's going to depend on your market, your layout, what kinds of finishes you want, and so forth. My contractor charged about double what the price of the shell was - my house is going a little over, not drastically, in part because I wanted quartz countertops, and because I decided to put in a couple rooms in the basement that I was going to worry about later (so as not to disrupt the cats when I do move), and because I will be adding in solar (which I'm contracting for, not the GC).

But it all depends on what you what do do, how you want your home to look.

It helps to know in advance where the light switches will be. They will design to pre-drill the logs for any switches, and the outlets in my house run along the baseboard. Obviously, pre-drill by any doors, and on the proper side! As for the kitchen,the exterior wall with the range on it is partially sheetrocked over that section of exterior wall, and they (GC and subs) attached cabinets to that, and did all their wiring so that area can't be seen, and it is effectively like any other house. So you can go IKEA or you can go custom for your cabinetry. (All my internal walls are sheetrock)

But you do need to find contractors who know how to deal with the fact that logs, fresh logs, will shrink a little over the first few years. Indeed, my log company insisted I go through GCs that have had prior experience with log, whether their log or someone else's.
