I want to help people by picking them up at the airport and find a living place for them before they arrive. I will also create a website to advertise myself. I need everything be legal from day one, and I can give my customers a receipt. Where should I do to register for my small company (do I even need to have a company for such a thing?) Which department of my local government do I need to go? Do I need to pay certain money to the government before even I earn money? Can anyone give me a clue? Thank you very much.
