It has to be remembered that the site, logo, business card, the appearance of a representative of the organization -  are the factors that always affect the opinion of potential customers of your services. At the site visitor's impression of the company is formed on the basis of a number of (user- friendly navigation, clarity of information, "interesting" supply) factors, the impression of the design and its ease of playing this important role. Having poor quality design, you risk instead of a marketing tool to get the anti-advertising (repellent, defamatory). The choice is yours. Either you choose a bright picture with screaming unclear how stuck graphics or designed on a modular grid interface, taking into account the psychology and perception of your site visitor.
