Create a team, but don't spend any money on player development. Play League games against the SNK Crushers until you've won about 15-20 of them and have $250-300K.
Fire all the players on that team, then power up until you have 15 Prestige for every player. Put the overage into Luck if you get enough points to exceed 15...pitchers should power up under "see other abilities".
Now create another team (your "real" team) and keep playing League games against the Prestige guys. You'll make a minimum of $75,000 from the gate for ten minutes or less worth of work.
