Content Management Systems (CMS) are a useful addition to any website where the basic content is regularly changing and updating — after all why pay me to do it, when you can manage it yourself?
If you can use Microsoft Word, then you have all the skills required to take control of your own website: add new pages, upload images and format copy.
Content Management Systems take longer to design and setup, and so this is only worthwhile if you are talking about a considerable amount of content which will be changed regularly. As rule of thumb I reckon if you are considering 30+ page site with weekly amendments, this is the most cost-effective option. Otherwise I would recommend a static website.
I build my Content Management Systems with WordPress, possibly the most tried and trusted software in the world. If it's good enough for CNN, the New York Times and several million other sites you can rest assured it's tried and tested.
I've build over half dozen CSMs sites with WordPress, and have built them from scratch to create a site that meets my clients specific requirements.
One of the most brilliant things about WordPress CMS systems is there is so much free software out there to add additional functionality to your site. Whether you want live online bookings, a members only forum, or fancy photo galleries - you name it, someone has programmed it - and it's available free of charge.
If you want the best CMS, you've got the best, WordPress.
Content Management Systems are only useful if you have the resources available to make sure the site us regularly updated and maintained by you or a member of staff.
