It is not about money oddly enough unless you end up with some local charlatans or︁ if they perceive you as over the top naive, otherwise no one even asked me︂ for money outright or god forbid bribes. Everything revolves around knowing a guy who knows︃ a guy and at most you're on the hook for a dinner or a bottle︄ of cheap whiskey.
The language is entirely unimportant if you have a local dealer and︅ shaker running things for you, half of the people you deal with are local minorities︆ who speak broken Macedonian so no one cares.
The main problem is that the people︇ that are left in the country are in general very dumb and lazy, with exceptions︈ of course, I'm generalising. You will be faced with frustrating incompetence and laziness more than︉ anything.
But, if you're not dealing with anything overtly shady everything will be easy and︊ fast.
While I was there Turkish gangsters and Ukrainan oligarchs were obtaining citizenship and passports︋ willy nilly and Venezuelans were using the country for money laundering. I even experienced some︌ minor inconvenience and more than usual checks when doing international transfers because the country's banking︍ system has a terrible reputation, funnily enough I had problems with Russia of all places,︎ Macedonia was too shady even for the Russians!
If you're interesting in banking over there️ I just checked one of the most popular banks (NLB) and they seem to accept Non-resident bank account applicants judging by the application form.
Here's the application form for reference:
