I really want to play a Warlock with a fiendish minion.

I was thinking. I could cast Magic Circle. Then summon Greater Demon. Then Planar Binding and then I would have one. But the casting takes an hour and the circle just gives disadvantage on attacks from the fiend. Which means they will probably just spam attack you for an hour and probably intterupt it. So what is the best way to get an infernal minion like this?

I want to plan a little adventure through Cania. But it gets a little chilly at -51C. Clothes probably won't be enough to keep warm. But I was thinking the spell Protection From Energy vs cold could work. But warlocks don't get that spell and if we don't have a player who can cast it how can we do it?

I added the City Hall but the option does not come up. Any ideas? The lot is on visitors allowed.
