Don't get discouraged if you can't get the strat down at first. Embrace the learning as one of the fun parts of the game. And once you figure it out you'll never look back. I had a blast doing guards from about 35 to 50. You'll make fat cash too.
Watch some of techmos' video's on youtube if you're looking for some guidance. My strat varied from his a little bit (taper versus invis), but what he does is tried and true.
