For those of you who have questions on expanding your business here is a couple simple ideas... i like to walk around and go door to door introduce my self,ask them if they have a lawn service, then simply ask for their business. some times you have to be a little pushy if you can tell that they are kind of thinking about it simply say "would monday or tuesday be a good day?" (set a date without them saying one) most likely they will say yes. Another form of advertisement that is effective is to concentrate on areas where you already have accounts i have done this alot and right now i have 17 on one street. try placing a add in the newspaper or getting a sign put up some where on a busy location. I find that most of these methods work for me. I am only 17 years old but I mean hey, if i can do this im sure you can also do this.
