Door to door is a great idea. Look professional and clean, get you a uniform shirt printed up would be even better. People will feel better about giving you business and recommending you to others once they have met you. Bring business cards with you. Once you start cutting bring flyers/ cards with you, walk 10 houses up and 10 down from the yard you cut passing them out. There is a book called Guerrilla Marketing by Jay Levinson I recommend you getting. It's full of cheap and great marketing ideas for small businesses. Word of mouth is everything, show up when you say you are going to show up, do a neat job, charge a fair price and be HONEST!! That puts you ahead of most just doing that. Also remember you are in the business to make money not payments. Too many lawn services fail because they put themselves to far in debt with equipment payments, a new truck to impress others with a big truck note etc... I would beg you to Start small pay cash and expand slowly. This could save you if the weather would turn dry for a few weeks. You will have less stress, you won't be desperate to take every yard as well. 1 zero that will fit in all yards but might take you 15 minutes longer to cut a big yard is better than 2 zeros sitting on a trailer and 15k + of your money tied up. More yards will come available a couple months into the season as all the new guys go out of business. Never buy their accounts either. Keep up with your collections don't let them get ahead of you. Good luck and God Bless!
