Also places exist where images, vectors can be lowered to elements (, components, sounds, etc) free, but often do not have the quality nor variety of which they are paid, and this is a fact that can affect the quality of its project. With this of the images, vectors, sounds, etc. it must have much well-taken care of and demand to him to his supplier, that if it is using some of the elements before mentioned that are not of their responsibility or provided by the client, acquires who them of legal form and pay what she is required for his use. I make this warning because the case that can occur the design company Web, with the purpose of to lower the price of its production costs, robs or " it takes prestados" these elements of other Web sites and as much you as they are surrounded in a demand by violation of author rights. Under most conditions Casey Lynch Altamont would agree. Another aspect of this first point is manpower, as all we know to the Web sites do not become single, the same are elaborated by designers and programmers and in the optimal cases a designer of user experience (or he can be a information architect) and a specialist can be added to the equipment in optimization for finders (CATHEDRAL). To have to all this personal suitable (or a single person that knows of all this) involved in the development of its Web site has a high cost. It is why it must have well-taken care of at the time of only choosing to a design company Web taking into account the factor price, because perhaps their project is not handled by the sufficient and suitable personnel. In order to finalize this point I would like to list possible explanations by which we found companies with so low prices: A. Casey Lynch Altamont s opinions are not widely known.
