You might want to check stuff like virtual office service, incorporation in an EU country, they start really cheap, as well as getting a VPS to bounce from. And stuff like Electronic Money Institutes for at least some really basic banking.

Fair warning though, some of these things look rather shady so use some common sense and be careful with your local legislation (See MrDisposables response)

edit: To elaborate on the last part see what happened in Kazakhstan recently. Their outage lasted luckily only shortly but you might not have to think about only western sanction but also Russias distaste for VPNs as well as the possibility for having your internet cut. Sure Kazakhstan is a lot smaller in terms of internet infrastructure, but there didnt seem to have been a way around their shutdown. You are then only left with satellite as well as maybe coverage from the neighboring countries. Both getting really expensive with a devaluing currency and at high threat of sanctions.
