Making $100,000 USD per month, no idea what to do with it 
If you already have 500k in a Schwab brokerage account, go see your Schwab financial consultant. They will assign you one, no charge, and in my experience they're sharp people. Sure, you can get a second opinion (or even report back here, maybe in chat?), but they will get you started in the right direction. I'd expect them to recommend a lot of index funds, just a bit of bonds or blended funds, all weighted heavily toward equities. If you're young and expect the income stream to continue, you can be fairly aggressive. Ask about the fees the entire way and you'll be fine.
