Blimey, started something there, i was only commenting on the domestic scene in my area. I wondered if it was difficult to pick up work because many householders are so scared of the whole youth culture that's about today. A couple of my customers were broken in to and the windowcleaner automatically became the first suspect. I think trustworthiness becomes an important issue.
Of course image is important, customers must trust you and the service you provide, unfortunately people make assumptions based on appearance, you may be the loveliest man to walk planet earth but if you have love hate tattooed on your knuckles people will make assumptions as to your character.
If groups of youths hang about the area at night, if you dress similar to them then the customer assumes you are the same, unfair but unfortunately true.
If you are nervous on the door the customer will pick up on it, and they will become nervous/uneasy too. You must have had this same experience yourself, you didnt buy because something wasnt quite right, and usually you just cant put your finger on it.
Customers need to buy you before they buy your service.
Think like your potential customers think, what would be important for them to use your service?
