Change of site design

Today was made a complete change of site design. Changed its structure.Now the site has appeared easy navigation between chapters and articles. Background image makes it clear that the site is devoted to construction.Simultaneously with the change of design had added some price lists for electrical and installation of local area networks.

Information from site

The site is gradually publish articles devoted to the description of services provided by electric fitters. This need is due to the fact that many consumers of such services simply do not know what they want, and negligent builders and others who provide services are inexperience of consumers. This infringes on the rights, agree. Therefore, on the site I posted price list for electrical work that will allow consumers to read the description of the types of work and get acquainted with the pricing.
