If you are looking for a platform that you can continue to update without having to engage a full-time web master, then you need a Content Management System (CMS). I am a big proponent of Joomla, and have been using it for many years. This site uses Joomla, as do all of my personal sites, because of the ease of adding, categorizing and scheduling of articles, availability of themes and useful add-ons. To quote from the Joomla site:

Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.

Joomla's appearance is customizable, with a variety of existing themes available from many sources. If you wish to have your own theme designed, I can help you with that as well.
