I have answered your question already.But in addition to what I've already posted in reply to 'Holly',as to why I prefer using a recruiter,of course a relatively reputable one,check another thread,'My English Club',for more info.If you read that,you'll see that in my view recruiters may not only be dishonest,but also schools that use them,not only TC's and private schools,but also public schools and universities!
As for English corners,if you dislike doing them,just like me,you can let a reputable agent find a job that doesn't require them on your behalf.That's what I do.So long as you have a white face,you don't even need any teaching references.Realise you power,and let your agent do the bargaining on your behalf,that's my advice.I know of two reputable ones.They'll even step in to back you up if the school tries to compromise you!
