What do you do with your customer base? Comprise a list and go down from the first name calling adn asking if they would like your services this year? Or do you just send a letter out to them filling them in on any info like price changes and such and to contact you if they would like your service again for the year? If you guys fill out contracts how do you work that send it with the letter and ask them to return it if interested or that maybe you will drop by to discuss some things and drop it off then? Let me in on the scoop =).
