Create a Wordpress Template

Hi all, We want to create a Wordpress template that is integrated in the current website. See the website here: [login to view URL] The blog for this website is here: [login to view URL] The Wordpress blog has to be identical to the main website (so it looks integrated). We want: -The upper menu and footer to be fully integrated. So when this changes on the main website it also changes at the blog -The layout of the blog must look a lot like [login to view URL] -So a overview page must look like "[login to view URL]" -A post must look like "[login to view URL]" -All designs incl. explanations are attached Keep the following aspects in mind: -SEO proof -Full Integration -Everything on frontend in Dutch -Widgets must work -Must work in all browsers Right now the above is the total asignment. When all goes wel we also want another thing with Wordpress... but that's for later. Kind regards, Jarno
