Help me build my first business

This campaign is to help me build up my first company, I live in a town where allot of both Icelandic people drive through and tourists and the roads in Iceland are not the best and allot of people who are driving through my town are coming from gravel roads on there new cars. And every day I see them trying to clean there cars by the store with the small cleaning station there. And it hurts to see them using brooms with flowing water cleaning there car and basically ruining there cars because people leave it on the ground and they are just scratching it all over so what I want to do is build a car wash where people can take their cars and get it cleaned properly so they can hit the road again :) I once did this here in my town but then I didn't have the place to wash allot of cars so I only cleaned car for people who lived in my town and business was good so now I want to make a real workplace so I can try to help people out on there trips and hopefully help tourists that are washing there car and when they return them the company who rented them can't charge them for damages on the car :)
