Do a lot of people or neighbors you know hire companies to wash their windows? And you say to yourself, I can do the same job for them for a better fee?
Now you can speak to those people and hand out flyers in their mailboxes and offer them your window washing service. Ask them what they currently pay to the window washing company and then you can lower your rate and let them know your rate and offer them a better price for the same job. Before you know it you will be making extra money and doing a great job at the same time.
