- Drupal

- Alfresco

We're looking at providing our clients with a complete pre-packaged CMS solution (development + consulting + hosting) and am looking for the best possible alternatives out there...
Ideally, it would makes our lives much simpler if there is a single service provider that can provision servers with the above mentioned apps
I dont want to spend all day on each one to find out with one is the best. Which one is the most user friendly and has skins so I can match it up with my other sites?
