You may need to research age care / disability homes and facilities specifically aimed at foreigners as that maybe your wife's only hope with her English language skills..
I believe these exist in Thailand but there are not many and the company would need to sponsor a working visa for your wife.
It's a long shot but at best but worth some investigation.
Or your wife may need to consider a career change to English language teaching as that's one of the few job opportunities available in Thailand.
But she would need to gain some kind of teaching qualification before attempting to find a job and again a work permit would need to be sponsored by any school willing to hire her..

Air freight will be quickest of course but very expensive.
Shipping by sea a cheaper option but very slow..
You need to contact some companies for cost estimates.
