What can I do to get out of Debt.

I became a business owner at 20 years old. I made a few poor business choices and then got behind on my monthly bills. I was hit with every expense imaginable as a new business owner, including heat bills over $1000 a month. I am also a single mother. On a personal level, I do not have much debt. It is on the business level that it seems I cannot keep up. I have recently purchased a home on a land-contract and I am current on my personal credit card bills.
