My boyfriend and I chucked it all and moved to Thailand a year ago. This is a decision you should not take lightly. We lived on Ko Tao for four months and in Khao Lak (Similans) for three months. First of all, I would never have done this except that I am half-Thai and have citizenship and speak the language fluently. You need a visa to stay in Thailand and if you are lucky you can get a year-long one and leave the country every three months for your 'visa run'. Most foreigners do not get this though and end up applying for tourist visa after tourist visa, leaving the country every one month, never sure if they will get to come back. The cost for this adds up over time. Research visas on www.thaivisa.com. It is easy to get a job on Ko Tao, however, keep in mind that you will be working illegally. Immigration does come to town rarely, but is this something you want to do? Also, Thailand is cheap, unless you are earning Thai baht, and meager amounts of it. Will your life be happy if you can only afford a dirty bungalow with bugs and the same cheap food (the better restaurants will be out of your range as they are geared towards tourists and their $)? We had a huge amount of savings when we went, and used most of it staying afloat. We finally gave up and moved to the city, where we both got great jobs and are very happy, but once again, there's no way we'd do this if I wasn't a citizen. Thailand welcomes tourists and their money but is not pleased to have illegal workers here. Ko Tao is a great place to further your diving education though, as long as you work on it yourself. Most of the shops are just money-stations and will put you through whether you are good or not. The diving is also seasonal and you should be prepared to move back and forth from Ko Tao to Similans, although Ko Tao does continue operating in the off-season. If you're both instructors though, and you live lean, you can make it, other people do it all over. Just make sure you plan well and have a back-up plan and extra cash. I've also seen people that don't have enough money to leave the country.
