Something I've been working on with the team I'm managing, I'm in season 6 now but I can't reach the play-off's in the Blue Square Premier.
I've not been a success at it but I feel it is improving you just don't see it..
Low wages, for example I took gambles on two Northern Irish strikers in the Blue Square Premier. Together, there wages are £320. They aren't good enough for this league but they do the job and hit the 20 marks. A consistent performer as a striker will help you in this way.
Being in the Blue Square South, non-contract terms however are the best for you. I'm talking very agreeable fees, not £700 for appearance.
The FA Trophy and FA Cup rake in a good amount of money for you if you can reach certain rounds. You need to do well in these competitions as I relied on the FA Trophy money when I lost in the semi-final and it delivered me a good amount of money to sort my finances out for the next season, despite me still making a loss. The Blue Square League money is poor but ending as high as possible is enough.
Get rid of a few higher earners, especially if they are on contract with their contract to run out within a year. Loan deals from League 2/Blue Square Premier sides, most likely their reserves offering 0% on wages, £0 on fee etc. Your aloud to play up to 5 in one league match (I think) so that will boost your finance that instead of having 5 players on the wage books you'll have 5 players for free who perform at a higher standard from a higher division.
Don't get a loan. I don't know how to but I don't recommend it. The board injecting money is one thing but if they keep injecting you need to reduce fees significantly as if they start to run out of money because lack of profit, you'll end up with a -10 point deduction and administration. A loan isn't the best to get especially if you mess up for example miss out on promotion you can put yourself in the gutter. Stick to what you have and work with it.
I have a feeder club. The board should of really got you one but if you don't have one you can request it via. the board and at the end of each season they'll help towards money.
Gaining results is most important due to tickets. If you can improve your league ranking it will boost ticket sales to help you slightly.
Hope some of this helps or re-considers your thinking over how your club is ran.
