A content management system (CMS) is a web application used for managing websites and web content. If you need to update your personal or company website contents regularly and without a webmaster or an IT personnel to do it - you need a CMS!
My choice for CMS solution is Joomla, one of the most powerful free Open Source Content Management Systems written with PHP. It is used all over the world for everything from simple websites to complex corporate applications. It includes features such as user registration, polls, newsflash, RSS feeds, content search and more. It can be extended further to include additional features such as forum, blogs, shopping cart, newsletter, events calendar, customize form, database & file backup, user profile, online magazine, file downloads, image gallery, directory listings, classified listings, search engine friendly URLs, etc.
I am a Full-Time Freelance Joomla Website Developer with more than 3 years experience in setting up website using Joomla CMS, getting the right functionality that you need for your business. I recommend using Commercial Joomla Template for your website as it give your site a real Professional look and feel, and many other features that you can't get for a custom design template.
You only need to pay for the implementation cost. You don't have to pay a single cent on the CMS itself as it is a free open source software. You get extra functionality offer by the 4500+ Joomla extensions available. I feel that this is the best and most affordable way to set up your personal or business website.
