If you are using natural cleaning products in your business, why not take advantage of the upcoming Earth Day to let people know that you are a "green" service provider. While Earth Day itself is Tuesday, April 22, there are weekend events at many locations looking for local business with an appropriate "fit" to come and set up a table, pass out cards or fliers, talk with the locals about what they do, etc. Some of these events are free to businesses, others might charge a nominal participation fee - maybe $100. The people who turn out at events like these already have a predisposition to use a business like yours.
