<i>I want to somehow use the money to make more money quickly (within a 2 year time span).</i><p>As others have pointed out the best asset you have is your ability to crank out mobile apps that people are willing to pay for. Not to burst your bubble, but even $24k a month is nowhere near enough for you to kick back and watch the returns flow in. The investment opportunity you seek--short term, high return, low risk--simply does not exist. If anyone attempts to convince you otherwise, reach for your wallet, because you are being had.
