6 years when I started up I had all the time in the world but little window cleaning work so I was as cheap as chips. Its all changed now, too many customers and my time is limited which means the opposite in pricing. I don't think the price is that important now for customers. I believe the most important is Trust and Reliability way above the cost. Once established and gained their trust then they will stick with you if you are reliable, that's what I have found out.
When you get a new customer and they complain about the cost then you know what's coming down the road so its better to price on the higher side to scare them off, that's what I have found out.
