Website build in Drupal

The intention is to build a scalable website using Drupal to hold information about a new scheme. the audience is likely to be large and varied. We already have a look and feel and a document containing all the information we need to present. The idea is to provide a home page containing a summary of what the scheme is all about, links to things like pdf docs, videos, a keyword search facility, how to use this site/FAQs and a form where users will be asked to select from categories like ‘sector’ eg. health, education etc, and ‘position’ eg. Volunteer, contractor, employer etc. (the content design of this form will come from us) Based on the result of that form, users will then be taken to a set of screens guiding them through their obligations and the timeline of what they have to do. There is a main version of the guidance, already published which will be consistent whatever the user chooses on the form. This would then be supplemented with the sector specific information that’s available. A more detailed spec' is available. We'd like to discuss the project in person or over the phone. Fluent English is a must and the ability to get to Central London would be preferable.
