Last year was my first full time year of mowing. I have approx. 35-40 weekly mowing customers. I am trying to come up with a basic format for my letter. Something like home you are making through the winter ok, price for this year(same as last), additional services offered this year, and maybe a few coupons. I am trying to make it sound and look as professional as possible. Any samples, formats, or basic structure would be greatly appreciated.
