Hi San D,
One of the most affordable and quality option is a state school. I currently attend a state school and am benefitting as a resident. Many state schools offer in-state tuition, financial aid and online accounting degrees. Another resource that I would highly recommend is to make use of CLEP exams to fill up on extra credits required for an Accounting degree. These are low cost ($100 for 3 -6 credits) and save a lot of time. This resource can be of help if you are pursuing a CPA and need extra college credits.
