Cactus TEFL is an organisation which provides information and advice about different TEFL courses worldwide. As far as I know (please correct me if I'm wrong, anyone!) they do not actually run courses themselves, but would be able to help you find a course.
When you've found a CELTA course which interests you, and also when you're looking for a job after your course, I would advise researching school - ask a question in this forum, or do a google search for the name of the school. Teachers who have had negative experiences are very quick to write about them online, so a search will often turn up some useful information about a school!
I hope this helps.
