Starting a startup need some talents to support

Hi everyone I saw a lot of pretty problems in my surroundings related to old age parents. Let me explain the problem in brief using an example, suppose there is a family having only one boy child, when turned 22 he got a job in a different city ( not in the city where his parents live) , so he has to leave the city where he was born. Now his parents are left in his old house and his salary is not enough so that he can carry his parents along with him. Now his parents have no support at his old house and also his parents are so old that they can't handle all the work so they need a person who can care for them. So here our startup comes into picture. Basically we provide the one caretaker of old parents in that case. Currently in India there are more than 3 million NRI who need that type of services and in India, a lot of families traveled in another city and they need that type of services. In future this business will definitely grow because nowadays a large number of people don't live in joint families. Note:- i am not supporting that old age parents should be left by the child, but there may be some difficulties. Suggestions are most welcomed :) See you all in the comments section.
