This Mini looks like a good project mate, has a lot of potential. You have made it clear that you dont know a lot about Minis, the first thing you need to realise is that this Mini needs a LOT of welding, you can see that just from the photos of the exterior, before you even come to the extra corrosion which the oversills will have caused.
It may be worth assessing now whether you want a project with so much welding, since it's gonna be a lot of work, before taking it apart any further, because selling it as a project in its current state should bring you a little more money for it.
I think its gonna need sills and the floors are going to be quite knackered (especially at the front) for a start, and then the flitch panels are almost certainly going to be shot (Behind the fiberglass dashboard which you have there will be two black fresh air vent holes, i think these will be particularly rusty) And then the other end of the sills leading into the rear bin, which you have photographed. This is very structural to the shell because its where the rear subframe mounts, and so you need to assess this and see if you have the ability to weld panels in these places first.
Don't hesitate to ask questions in the other parts of the forum and in here, because you will get answers, it's great for that here.
On the other hand, I dont think its un-doable by any means! It isn't going to be a walk in the park but we've all seen far worse! so dont be daunted by some comments that you may come across
Keep us updated with more photos and good luck, I'll be following
