I would suggest you start with mundane means. Budgeting, cutting excessive spending, and looking for a job, any job.
There are a few spells on here, the money jar (I think that is the name) is pretty good. I find it helps to write spells of this nature myself as everyone has different needs on this issue. Work up something small, perhaps with a green candle, some cinnamon, a red sharpy (the color doesn't matter), and a copy of the bill or bills. Most of this you can buy at the dollar store, the copy of the bill could be an older one. Write out the spell as you see fit, see yourself paying the bill off or at least the monthly due amount, write Paid with the sharpy (I like to use red for this, but whatever you have will work, even an ink pen). Either bury or burn (safety first) the bill and know that it will be paid on time.
This has helped me many times.
