Not enough hours for airline entry after modular course

[r200biggles]

I researched a lot lately on the options in flight training, type of training, how to fund it etc....

I have one concern though. When you follow the integrated course for example, you graduate with at least 250hrs. However, the vast majority of the airlines seem to want at least 1000hrs, some airlines requiring 1500hrs unfozen ATPL (which means at least 500hrs on a multicrew aircraft).

Of course a few very small airlines do not have minimum hours requirements, but these pay a wage which would not justify borrowing large amounts of money for the training.
How do you fill this missing hour gap?

Thanks for any replies.
