Startup Idea : Better choice in healthcare

I'd like to build a website/app where people can search medical providers (primary care/specialists) / facilities (clinics/hospitals/care centers) / prescription drugs / pharmacies and find out which insurance (insurance companies and plans) would cover and how much they would be covered under a specific insurance so that they can make better decisions on choosing plans based on their needs and budgets. People can also login to see their current plan and compare with other plans by searching those.
