If your cash is running low, and you are not expecting
any fresh income from sponsorship or prize money, 
you should think about asking the bank for a loan. 
This should be a short term measure only, because 
debt repayment on large sums will probably bankrupt 
you. Beware, if you take out a loan on top of an 
existing one, the bank will increase the interest on all 
the money you owe.
