150 credits

Hi – I currently have 122.75 credits, with over 40 in accounting and auditing.
I need extra 28 credits… What would be the fastest/cheapest way to go? I am international candidate, so I am getting a bit lost in all the options and information read online.
I found a couple of programs, including one in North Alabama University, but they are mostly accounting classes, so I am afraid they will be taken as duplicate credits and won’t do any good for my 150 goal..
