The one thing I've learned is that people that are "self-made" and have a ton of dough, love talking about it. They love it when people are interested in their "white people struggle" to the top. Their accomplishments, and their future goals of grandeur. They love when people can relate to that struggle with their own fantastic rich guy anecdotes. After a few stiff drinks they're spilling their entire business plan from start to finish.
So when I started making good money and wanted to meet like minded people I hit up all the expensive clubs. Not your teeny-bopper nightclub spots where all the rich kids hang out to spend Dads money. The clubs where "Dad" hangs out. The classy, suit and tie, you don't get in here with tennis shoes nightclubs. Met a lot of great businessmen (and women!) there that ended up giving me a ton of great opportunities.
Key is don't talk business while you're there. They are there to unwind. Just buy them a few drinks (no homo), shoot the shit and exchange cards. Keep in mind they're probably drunk as shit so they won't recognize your name, voice or anything else on Monday when you try and call them.
So pretend like its some hot bitch, don't call right away. Become a "regular" at the club and eventually they'll recognize your face, and your voice. If you're even half way charming, and don't look like a homeless person they'll begin to like you. Then and only then start hitting them up on Mon-Fri 9-5.
That looks like some pretty good advice.
I'll add a tidbit. Buy an expensive watch. Actually, buy a few expensive watches. (You said 6 figures a month, OP.)
I remember when I thought it was completely frivolous to pay $100 for a watch. Watches that tell time cost $5-10. Not only was it frivolous, but also pretentious and rude.
I eventually bought a really snazzy watch for $150 after a friend advised me. I realized that the bank stopped questioning me about checks, etc. (Banks have "can lighting" so they can scope jewelry, it turns out... or maybe so jewelry wearing people will feel better about themselves... motives aside the result is the same.)
A few years later, I realized something else. If you wear a rolex on a regular basis, the only people who notice are people that wear rolexes. Those people have a good idea of what you are wearing, even though no one needs or wants to talk about it. You'd think wearing 5k on your wrist would be an invitation to get robbed, but it can also be an indication that you aren't fearful. Think ghetto crack dealer rappers, with giant gold on their necks. I don't try to overdress when visiting ghettos, but I don't try to under-dress when going average places.
Last of all, a good watch is a store of value. Provided the the world hasn't imploded, you can sell it. If everything crashes around you, you don't deserve to wear a president anyway. You're wearing a chunk of start up money.
