You're insisting that you be placed in one of the major "party zones" of the city. You're clearly being way too picky, holding out for something that will suit your (very specific) needs. You've been offered positions that had "terms that weren't to your liking"? What were the terms, if I may inquire?
Are you a qualified teacher? If not, what gives you the right to hold their "terms" to your unreasonable standards?
If it's your first time here, you do like everyone else, you start at the bottom rung. You get something that's standard to what most first-time ESL "teachers" get. If you're not a qualified teacher, you're not entitled to anything beyond what most of us get.
Don't get me wrong, you're entitled to what's fair, so don't settle for a slave contract...but if you keep expecting some ideal job that's going to give you minimal hours, maximum pay, and a cozy place in an area that puts the conveniences of sufring, beer, and women within arms reach...well, you're setting yourself up for failure.
If this isn't your first time teaching in Korea, then disregard what I said and do your best to get something that matches up with your experience.
