The reason why you can not get anything normal in Thailand is the same reason why many successful Thai women over 39 also can not get anything decent. You simply can't find the time to go weed out the potential candidates.
However, I must say that the original post stinks a bit of fraud. If I am wrong, I apologize.
If you speak Thai that means you socialized with a lot with Thais. Surely there would be a freind of a friend who would set you up with someone by now. So what else is wrong besides the long working hours? Even Elon Musk managed to father 7 children. I don't buy this story. If you are serious my wife is a friend with a pig farm girl in her 30's. Beautiful and very rich. No need for farang money.
