Bitvark http://drupal.org/node/1266792

BitVark was founded in November 2007 as a web agency specialized in Drupal, as its founders follow the CMS from the earliest versions, developing daily graphic themes and new modules.

BitVark is a philosophy totally different from what the other agencies usually take. Our clients are followed step by step through all the stages of product realization. Our associates closely follow the client and puts the center of the project as a true protagonist.

BitVark is synonymous with ethics. The software we use is Open-Source, a world view that Bitvark supports and is committed to promoting widely.

BitVark also presents a number of interesting proposals to cultural associations and non-profit.
