I was brought up in this industry when this old adage was prevalent and it can be applied to any business: "Three things go into a
sign, price, quality and deadline. The customer picks two, you get the third."
Any way you work the combinations, it works and protects your business from a lifetime of playing catch up. Those that try to think they can outrun giving the customer all three and ignore their overhead and quality of life, eventually run themselves out of business.
I just got a call from a mega-mega multi-millionaire who owns one of the largest vineyards in our area. They are opening a restaurant at the vineyard and want some extra signage on what is easily a mile long frontage of their property. As I started running out some cost effective options to him, he shared that his marketing director had ordered a couple of banners from Staples, even though we had done other work for them. The Staples banners had disintegrated into shreds by the high winds that prevail in the area shortly after installation.
He stopped me short and abruptly said, let's not waste valuable time on run of the mill options, we've been down the cheap route, we called you because of the fallacy in the cheap route thinking.
Moral of the story, only you can choose how you want the vast majority of your customers to perceive your expertise level. The one's that make you want to take a shower after dealing with them are better left to others with less self-respect.
