My museum is reader for change, and we are looking at Drupal. Any developers?

I work at the Contemporary Jewish Museum In San Francisco. Currently we are using Joomla for our site, and I am not happy about it at all. Aside from the issues with the CMS, the integration of Raisers Edge, NetCommunity, and Sparx is ridiculous.

I would like for the museum to start looking for something other than Blackbaud products, CiviCRM or the like, however the idea of just changing over from Joomla to something like Drupal is a good step.

So my question is if anyone here knows a company/developer than can help us with the move to Drupal from Joomla, add our theme and branding to a new drupal theme, and integrate Blackbaud as well as exhibition/gallery/calendar features that we will need?

thank you
