Drupal-Pros; Freelancer​/Agenturen für größeres Drupal multi-language Projekt

We are launching a website in 3 target markets:
Germany (.de), Netherlands (.nl), and Great Britain (). Each domain must host distinct content within identical layouts, and translations must be available in the required languages (Germany: de|en; Netherlands: no|de; Great Britain: en). The site must also feature an administration interface that is easy for non-technical end users to manage.

After the pilot launch the website will expand to approximately 19 additional markets (INTL, FR, ES, BE, LU, CH, DK, AT, IT, SE, PL, AU, CZ, RO, SL) with new languages, so the underlying structure must be solid, maintainable, and user-friendly.

Develop the site structure, selecting suitable modules such as:

• Internationalization / Localization
• Organic Groups
• Domain Access Module
• Panels or Context (or both)

Create or use a Workbench-like module to allow content editors in each market/language to edit only relevant content without confusion.

Implement roughly 10 types of page templates, including:

• Homepage
• Content page
• Microsite template
• History template
• Map template
• Landing page
• Download page
• Webform page
• Tag pages / Category pages
• Campaign page

• Breadcrumbs
• Advanced search
• Tag cloud
• Top links (navigation)

• Call to action blocks

• Video & Audio (flowplayer)
• Slideshow
• Picture + Text teaser
• Banner ads

• Share buttons on social networks (Twitter, Facebook, Pinterest)
• Twitter feed integration
