How can I turn $1,000 into $80,000 in two years?

It's worth asking. Let's say I have $1,000 now to invest. I'm willing to take risks with this money and track the investment-- maybe trading stocks on a regular basis. Does anyone have good advice for me to turn my principle investment ($1,000) into a down payment for a home ($80,000) in about two years? I'm willing to throw in up to $200 a month on top of that (for an extra $4,800 buy-in).
