Without cash you cannot do anything but wait.

Any good ideas on how to make some money?
Play a lot of friendlies. Eventhough they don't give you a lot of money, it's still a few bucks coming in regularly. It doesn't really matter if you play at home or on the road, as the benefits for friendlies (and national cup games) are splitted equally between both teams. So you'd better play in the biggest arena and/or best team's place to maximize the number of people coming to the game, and therefore maximize the profits.
Having a strong 'Human Ressources and Economics' department also helps to bring more people to your arena. And it obviously helps to get better sponsors by the end of the season.
The other way to get money is to sell players and/or staff. A bit risky, as you pay a tax no matter if the player is sold or not, so you'd better be sure someone will buy it, or you'll end up loosing money. In the same time, it can be very lucrative when you get lucky. I'm not that high on using the market to make money though. Firstly, because you need luck, and it's not something you always have. Secondly, because it's not really the reason of existing of the market, although several managers try to use it that way. If you've got a good Human Ressources department (bringing a lot of staff) or a good sports academy (bringing a lot of players), it might be a way to explore though. But be very cautious with it. You can win a lot on the market, but you can also loose a lot (player/staff not sold -> tax + you keep the salary on your daily expanses).
Anyway, the first season is tough for everyone financially. Low sponsors, as we are just starting teams with low team strength, so it's hard to get as many bucks as we want. That's why every single buck has to be spent wisely in season 1. Even after that, of course, but especially in season 1.
