keep it nice tidy simple you could leave a space on it to add a price to as your walking up the path that way you only get phone calls for genuine custys that are ringing to book you not just for a quote
You could but the danger is to underquote if you dont see the monster conny at back, or the lack of access or the fact they want it doing 4, 6 , 8 , 12 weekly, or frames as well bla bla bla
Just knock the door
If not in leave leaflet and go back
I know many will say they built on leaflets but i reckon they spent more time posting than i do knocking for same work... and if you are in a heavily saturated area its gonna be hard many leaflets will fall on people with a wc, just look for dirty windows and knock away
