| Welcome to YD Craig.
There are those here who instruct part time for fun, for money and some full timers as a job.
Yet I suspect most of us have non diving jobs as it is an easier way to earn a living.
However if you have a dream, who knows how you would feel in the future if you did not give it a go. "If only" etc. Although, from reputation, I hear that Pattaya is not the nicest place in Thailand. You may also find that locals are willing to work for less than you. I have seen European/American dive guides in Thailand struggling to save enough money for the flight home.
So, potentially a few downsides to it, but what do I know. I've never wanted to do it, so haven't.
Good luck if you give it a go.
