Define "making a living". That means different things to different people. Personally, I can't begin to fathom living expenses of $2K per month. Is his goal $2K per month (average of $100 day) or $60K-$100K (mid-point average of $320 per day)? Significant difference.
Either way, an account of $30K is more than enough to accomplish it, IF his edge translates to the futures markets he wants to trade AND his money management skills are as you stated (and that trading was with real money). One or two contracts is definitely the place to start -- ten contracts is really a lot of pressure. To quote Marty Schwartz, "I don't feel the same pressure when I own 100,000 shares of stock as when I own 100 S&Ps." The scale is obviously different, but the idea is the same.
Since his money management is apparently in place (again, assuming he was trading with real money), his simulator results should not be too misleading. He should be able to determine from the simulator whether or not his edge translates to futures successfully (i.e., before trading real money). If it does, then he should be in good shape.
A good question has already been asked: If he is successful with equities, why change to futures? There's a lot of value in working what works. I would really like to trade spot forex, but I currently suck, suck, suck at it. Futures are what I'm good at, so I stick with them. Just curious...
