It never fails to amaze me that some people are reluctant to believe that good design is often less costly than bad design. Of course, I don't just mean the overall cost of the services and product, but also the return on investment.
Take simple window graphics, for instance. If you hire a Designer, the cost for the actual design is usually based on industry standard pricing guidelines, and fluctuates slightly based on the competency of the Designer. In most cases, however, the price for the actual design falls in a very specific range. The cost for fabricating and installing the window graphics is also more or less a fixed cost. Only varying slightly depending on the vendor. Some vendors offer design services for free. Beware, the cost of those services can sometimes be hidden in the total cost. Plus, the designers they have on staff are typically not the best designers in town. (My apologies to sign vendors, but in my experience it's true.) Most of my examples of bad window graphics are from the websites of sign companies.
In any case, these photo examples of beautifully designed window graphics versus very poorly designed window graphics clearly show which is the better investment. Poorly designed graphics can actually hurt a business in the long run. Which would you want for your business? See my point? I'll say it again, the price of good design often costs less than bad design.
