I need to build a website that keeps the content & appearance themes separate. I figured that a content management system is the best way to achieve this goal. I expect the user base to be hundreds of hits a day. What is the best content management system for:
- Speed (given the low visits)
- Development & maintenance (cost of hiring developers & maintaining the system, ability to upgrade to new versions of the system while keeping my customized code separate)
- Availability of free themes
