help with BA Business plan

[Micromist]

I'm wanting to earn a business degree.

I need a degree for a promotion at work I'll be eligible for in a year so I'm hoping it's humanly possible to complete by then.

Budget: I have a max of $7K saved up but qualify for Pell and will take out student loans if absolutely necessary. I'd like to go the cheapest route possible, but will consider spending more for easy and fast.  
Commitments: Just my work and my pets. I currently work full time and can work on my studies part time or in the evenings/weekends.
Dedicated time to study: I think I can fit in at least 20 hours a week, maybe a bit more. My weekends are entirely free but I'm stuck late at work a few times during the week.
Timeline: I need a degree for a promotion at work I'll be eligible for in a year so I'm hoping it's humanly possible to complete by then. I'd also have more and better job prospects with a degree, so faster is better.
Tuition assistance/reimbursement: My job doesn't have tuition reimbursement.

I'm not a great test taker but I'm worse at writing long papers, so tests are preferable. I understand writing is part of most degrees, though I would likely do best in a program with more tests and less writing.

Most of my credits are from 15 years ago. Is there any issue with old credits transferring?
