With a law degree + working experience from home I should think that many other (better
) avenues are possibly open, it should not be to difficult for you to get to grips with a few areas of Thai law, many expats seems to be in constant need of solicitor assistance here in LOS
so Law offices catering for expats might be a good place to look.
It's not to hot in the real estate business right now but that could be an area to look at, marriage, divorce hot all the time, set up of small businesses aso.
I would think that quite a few company's would look favourably at someone with your background.
Anyway welcome to the board
