THANK YOU FOR YOUR CONSIDERATION!!!! any help will be greatly appreciated!!!!!

My girlfriend and I are now considering moving out to Thailandafter hearing about all of their adventures and experiences teaching.
I was curious as to what the prospects look like for a(24yr) who has a BS in Biology with a concentration in secondary education andprofessional teaching license in Thailand? I have taught Biology, PhysicalScie, Anatomy&Phys in public high schools here in the states as well as aseason teaching marine biology and environmental science in the florida keys ata marine science institute. I also volunteered my time during my studentteaching coaching the varsity men’s & women’s track team. Would I be able to obtain work simply bypounding the pavement? Would I need a TEFL/TESOL?
My girlfriend just recently graduated (23yr) with a BS inexercise science with a concentration in outdoor education. From what I haveread I think that a TEFL or TESOL cert would help her out since she has noformal teaching certification. She has been looking at the American TESOLinstitute in Chiang Mai for the in-country 4-5 week course, any have anythoughts or suggestions?
I planned on flying over with her when she leaves for hercourse(oct20?) and sharing the living accommodations that the program provides,$150usd each. While she is in class I planned on pounding the pavement resume,diploma, teach cert in hand in search of work in Chiang Mai. Is that areasonable aspiration? I have read that most people do find work once they havereached the country, I have interviewed with agencies via skype but they allseem very suspect. A lot of the schools I have contacted all prompted me toalert them once I was in country for an interview?
Would it be possible for some with a teaching cert inscience to find work teaching SCIENCE, math, English without a TEFL in ChiangMai? We are both looking to try and find work in the northern provinces, we areboth avid rock climbers, trail runners, hikers and love the mtns.
Does looking for work as a couple help the odds? I have readabout some schools preferring couples due to their increased level ofcommitment to staying the duration of the contract…is this true?
We both plan to have at the very least 3k saved up each uponarrival, excluding airfare and her tesol course. Is that enough for us tosurvive a month? Would it take that long to find work?
I am no stranger to living cheaply and modestly. I spentmany months eating canned black beans and chz sandwiches while I was incollege. What is a decent salary for someone with a teaching cert in sciencefrom the US? Or her BS in exercise sci with a TEFL? We plan on living togetherand splitting housing, utilities, etc. we also plan on using what money we maketo fund our climbing, hiking, running, spearfishing trips. We are not bigspenders, partiers, or high maintenance people.
THANK YOU! Any suggestions or tips will help out! Hope tojoin all of you soon!!!
