The more games you play the more rep you get.
You can sell some of your players for half price by going to your profile adn clicking on some players then click sell at half price this will give you some money.
Try just entering friendlies to boost your training points so that you can level up the players before entering cups. If you play friendlies you dont earn much rep if any so the games will constantly be the same difficulty and it gives you time to rank your players up and then when they are ready to be entered in cups you will find they go further in it and therefore increasing your money.

Also try making bets once in a while only be careful on matches which are hard to call.

Hope i helped.
