Pay for services, not software

Open-source content management systems: "
With no outlay on software, an open-source CMS leaves the majority of the project budget to address critical supporting tasks, including:

* customising the CMS to match specific business needs
* integrating the CMS with other business systems
* developing templates, stylesheets and publishing code
* reviewing, restructuring and creating content
* conducting usability tests, both on the site and the CMS
* providing training to authors and end users.
* conducting communication and change management activities."
