If you want a custom designed content management system, you can start a new website from scratch, or use your existing website.
For conversions, we take your existing site and convert it top a Wordpress theme, or integrate it into Sitemakin CMS or Bootstrap Blogifier. Afterwards, the site will run just like any other CMS.
Wordpress is the world leader. They don't need to advertise DIY builders and their market share blows away the competition in terms of websites built. Unlike many other platforms, you own your site with Wordpress and are not renting a tool. This way, it is easy to control your web developer, content and hosting.
Sitemakin CMS allows you to make custom pages to any html / css site that you can edit right away. It is a fast option for simple sites, but not intended to develope large websites.
Bootstrap Blogifier allows you to take a static HTML / CSS site and add a blog to it. It is a paid option to using Wordpress and is easier to implement.
