Obviously this is information I can fish from the web, I've searched some different sites, but none of them seem very reputable, so I was hoping some people with actual experience could answer me here.
Can I direct you to
https://www.streber.st/? It's a website by a guy who arranges and manages exactly these kind of things for his customers. There are heaps of information on it, I've read through much of it, and I have the impression the guy really seems to know his thing (I base it mostly on his responses to comments and on articles when he touches on things that I personally know about, such as managing data security and privacy).
The catch is that he's doing it anonymously, "just for fun", and so you won't be able to hire him or ask for a solution for your specific needs (he's only taking on clients through trusted intermediaries). At the same time, this is exactly why the info you'll find there is so much more reliable than all of those other "I'll tell you wise thingz, now here's my price" sites. While you won't find the exact solution, you'll learn enough to steer clear from the fakes. There's also a (not too busy, but neither dead) forum on his site, where you may post this same question.
You may find this useful for getting prepared for the bullshit you'll hear: The Real Deal about Nominees -

Here are some articles about the actually hard part, banking:
