How do you ask people to let you cut their grass for money?

Go to their home and say something along these lines (improvise): Hi, my name is . I am offering to mow your lawn for a small fee. Would you be interested? OR Hi, my name is . Would you need someone to mow your lawn? It might be best to go with a business card. If you don't have one, then print up about 50 copies of paper with your name and number, so they can call you in the future. Some people may need to think about it before they commit. Be ready to provide references if asked for them. Good luck!
