as this season will be the deciding factor in my future in this business, i need to make a huge effort, and either sink or swim. im tired of going on a miilion estimates, and wasting time on people who r not really serious, or are price hunting to save that $2. so, what do u think: send a notice to customers saying how we appreciate them and so on, and offer a cash back incentive for referrels. im thinking $20 per customer who signs a seasonal contract. or perhaps a free service? what do u think, would this create incentive to to refer us to neighbors, friends, etc. ?
