You probably need some kind of content management. The reason we say this is because the best sites on the web, and the ones that generate the most traffic are the ones that regularly add and change their content.
For most sites we use the WordPress system for content management. It’s by far the easiest system out there to use and it’s very powerful, so we use it whenever possible.
For most sites we recommend using up a CMS, sites that are full flash sites though normally wouldn’t use a CMS because the cost is very high to set up a custom CMS for a flash site. If you need to change the content on your flash site yourself we can bring the content into the site with XML files, which are text files that you can edit yourself to add more content or change your content.
