Development of backend system for Website for Up and Coming building company

Site is to be developed for North Corp Building and Construction in North Queensland, Australia. Design and frontend coding is being developed inside another project, however if you can do both, feel free. System is to be developed inside latest version of Wordpress as a CMS. All strict wordpress coding principles must be adhered to, without taking shortcut’s which can break in upgrades to the wordpress core system or used plugins. While you will be supplied with templates for some content, you will need to have design sense enough to style the pages with class to match the quality achieved with the design itself. [Site content] – help with menu/content items for page - Home page [as much text as possible must be editable, even if done with an options page] - About the company [page] - Team information (staff photos/bios) (custom post types with taxonomies) - Products (with sub nav for products) (custom post types with taxonomies) - Projects (past and present) (custom post types with taxonomies) - Blog - Documents (custom post types with taxonomies) - Testimonials [page] - Contact Us [page + plugin] - Sitemap page (generate with plugin) [You will be supplied] - Content for the pages - Logos - Staff photos - Some photos - Html/css/js for: Frontpage, 2 different styled content pages, blog design [Minimum plugins] - All in one SEO package - Google XML Sitemaps [Site deliverables on top of wordpress build] - Correctly optimised for wordpress [login to view URL] - [login to view URL] (generated by system) - All coding must meet modern standard, and be SEO friendly (correct use of headings, paragraphs etc) [Browser/Coding support] All elements will be be coded to either xhtml transitional & css 2.0 or html5 – css 3. (depending on template coding.) Needs to work correctly or fall back gracefully in: - Chrome (latest, couple of versions back) - Firefox (latest, couple of versions back) - Safari (latest, couple of versions back) - Internet Explorer 7.0+ All coding needs to be done in an isolated way, so elements should not rely on other elements to display / be positioned correctly. If a section needs to be removed, it should allow for this without major recoding. (i.e: div-itis is not always bad).
