What you're looking for is a get rich quick scheme, but you're not going to find one here (not a legit one, anyway).
Here's an idea: have your cousin in the Illinois state legislature throw you some lucrative contracts. That's the kind of get rich quick scheme that works. Don't have a cousin in the Illinois state legislature? Then you'll have to do something that requires more time investment if you want both a reasonable chance of success and a high, rapid ROI.
It seems to me what he's looking for is more like a "get-rich-investment". He has time and money to invest in something, and wants to use them to maximum advantage. No need to belittle the post, it's quite valid.
