While making a site using web templates a person can make a base template file where it is possible to specify the non editable and editable regions separately. People also prefer the template based sites as they tend to be search engine friendly if the template is optimized properly. One can take the help of certain web site design software like Dream weaver for creating website templates easily. However, it also helps if one knows HTML to an extent.
When it comes to the high-priced website developers, they are going to have a reputation to back them. They are going to have a portfolio of professional websites they have created that are going to speak for their work. High-priced website designers are going to have people who could vouch for them as well as have a very strong web presence. This is the reason why they are going to be priced so expensively, because what you are really paying for is a degree of certainty, not necessarily superior quality.
