How to get out of a lease?

I had signed up for a lease agreement in april of this year. for one year agreement till next april. My boyfriend has lost his job and I have been sick off and on so money is tight and we really cant afford to live there anymore paying $701 a month. We have talked to the property manager and the only way we can get out of our lease agreement is either Military orders, Move out, but still pay rent till someone can move in ( which we all know they would not work on finding someone till allot heir empty ones were full) or find someone to take over the apartment. We have been trying that. Posting it legally on facebook account and Craigslist. But does anyone know any other way to get out of it? We live in Florida and according the place they tell us that in Florida there is no termination fee. Which would be wonderful, So for now we are cutting corners the best we can. But...any help?
