Startup Idea : Marketplace for long term home care

Problem 1: Every year, millions of students travel internationally for schooling. Every summer/winter breaks they have, they need housing & accomodaton. Problem 2: Cost of home care (nanny, au pair, elder care, etc.) is going up every year in developed countries. They need an affordable home care solution. Solution: AirBnb for home care. International students provide home care to host families while the host families provide housing, food, and nominal stipend.
