While there are many commercial Content Management Systems available (e.g. Wordpress, Joomla, Drupal), they are all crippled to some extent by their attempts to be everything to everyone.
A bespoke CMS ensures that fake 'phising' web-pages cannot be created - the CMS only affects content within existing design parameters.
The admin pages are far simpler and guide you to perform just the tasks relevant to you
A website constructed using industry-standard HTML and PHP is fully portable
We have years of experience with creating all sizes of website and even the smallest of site can benefit by having some areas for CMS, even if it's just a news page. In terms of both initial outlay and your time in administering the website, a bespoke CMS really can work out cheaper than even a 'free' commercial CMS package.
