Give a percent of your revenue to charitable causes.
An innovative way to do this would be to have a counter for customers to vote for a product or service that you are prepared to offer as a gift for charities. This way the customers can see that their action is getting something for a charitable cause.
The more you give the more reputation you build among society, which in turn will provide more business for you.
