Build WP website - 10 - 20 pages. Responsive - May use theme.

I need an indication on cost and time to develop a site for: [login to view URL] We have just finished new corporate identity and photography. Schema for new site as per attached PDF. Would be a standard WP site. With Staff Listing – may use plug In for this. Copy supplied. We will have photography. All supplied at once. Would like three - five mock ups of home page. I wonder if one of these should be a scrolling home page with sections that relate back to top level nav sections. And a few options for the landing page for each category/key pages. And if we provide all materials – what turn around for designs and build?
