New teams start with 300k, and get an extra 50k for the first 3 weeks (iirc).
$450k is more than enough to buy a decent trainee or two with star potential, and then a few oldies to balance the squad.
In Div IV, expenses are a not an issue. The chances of promotion this season are slim.
The other option is to train well for 1 season, then sell next season and buy players who are being sold after the draft. Due to the flood of players, there's always a bargain if you look hard enough.
