Formally qualified isn't in itself important. Parents don't have formal qualifications. People with formal qualifications can in fact sometimes be terrible at caring for vulnerable people. Trustworthy? They can be found. The world would fall to pieces overnight without trustworthy people.

Having the money available to employ help is the key. And that doesn't come cheap, because it's demanding work. Clearly enough isn't forthcoming from public funds in this case to meet the need, hence "affordable". If that's so, shame on the society and the country involved. "Could be taken care of"... sounds a bit like the language of the workhouse.
