Yes good idea, there is no special training needed, it is surprising how many Thais are willing to live in, no rent to pay, and take care i.e. Feed, shower, and dress someone. we i.e. my Wife, found a lady to call in on our friend every 2 days for just 4k a month, as he eventually needed 24/7 care She eventually moved in with him, so she was 3k a week better off, no bills to pay ether. Ask around your friends wives if you can.
