Are there any ACE grad classes?

To qualify for certain jobs, I would be eligible by taking 18 credits of graduate school courses in accounting, business, business administration (MBA), finance, marketing, economics or other directly related field.

Are there any ACE options or is ACE pretty much limited to undergrad?

If there are options, what is the cost efficient way to get them on a graduate school transcript?

I know that I could just do WGU and and knock out 6 classes in 1 or 2 terms, but that would be a bit expensive.
