Another tip I have found works well...
When giving out quotes, get a phone number and the name of the person you spoke to. Then if they haven't got back to you within a couple of days, give them a call.
My wife did 16 quotes a few months back and followed them up with a quick phone call a few days later. She got 12 of them as customers and another just wanted fascias cleaning.
People mean to call, but just don't get round to it. Wish I had used this method from the start. I'm sure I'd be over the 300 mark had I.
I got a call the other day from a leaflet I dropped on my first day knocking, definatley worth leaving one.
Also on my next lot of leaflets I'm going to get printed on there (probably at the top) please save me or pass me to a friend. You never know.
Also when someone rings for a quote, ask them where they got your phone number. I like to be able to tell my wife that I got another job because of a leaflet she left. The feel good factor.
Get some free advertising on google and yellow pages. You might get pestered by them (I haven't) but its worth it. I put an advert on google and have had 6 emails from people wanting a window cleaner. Each one is now a customer. If the can be bothered to hunt you out, they are worth having.
