Fair Vote Canada: CiviCRM Implementation and Support
Fair Vote Canada is a small NGO, has been around for about 7 years, and is a public interest lobby group for proportional representation-type voting systems in Canada. If you care about democracy, then they're worth supporting.
In April 2008 I helped Fair Vote Canada with a re-implementation of CiviCRM to manage their donations, membership and communication with their constituents. See this case study for a detailed look at that process.
During summer/fall 2008, I helped migrate their mail to google apps, updated their Drupal install, cleaned up their disks, and eventually switched the site over to my server during the October federal election. Also during this time, I provided ongoing CiviCRM support as they extended their use of CiviCRM and continue to work out the details of how to use it.
In spring/summer 2009, I migrated them back to my server when their existing host quit, upgraded the site to Drupal 6 and CiviCRM 2.2, and implemented a new theme.
