I can personally vouch for LinguaEdge, an online TESOL class that's BBB certified. I realize you're trying to get into a school to study ESL/EFL professionally, but if it doesn't work out, you can get a TESOL certificate from http://www.linguaedge.com/. I took the 100-hour course and finished it in a month and it cost close to $200. I was working on the course almost everyday though just to let you know so it could take you longer. Make sure to do the trial course because LinguaEdge will lower the cost of the course if you do decide to enroll after completing it. Good luck with whatever decision you make!
