I never spend any money on design, black and white word document, 2 leaflets per A4 page. I always get good results.
Keep it simple; Name, YOUR ADDRESS, local phone number, service offered. While delivering leaflets always shut the gate and never walk on the grass. Little things like that may slow you down slightly but you will pick up customers because of it, if the natural path from one house to the next is across someone's grass guaranteed every does it, postie, paper boy etc. It may well wind her right up, she sees you respecting her property and you are off to a good start.
