Design integration of 5 subdomains with open source software

This project is to integrate the design of five subdomains to the corporative design of the main domain. It is a simple project. Concretely, the job consists of adding the same header and footer in each template of each subdomain and also change template colors and fonts to fit with the corporative style. The idea is to make something similar to this website: main page: [login to view URL] forums: [login to view URL] wiki: [login to view URL] (archlinux is not our site and we don't have any relation, it is just an example) Note that the header is always the same for different open source software. It is necessary to modify some PHP, TPL and CSS files in each subdomain. So, given a [login to view URL], a [login to view URL] and a css file defining the corporative style, your job is to include that files in each template. We want that, when we modify something in our files (header, footer, css) this modification impact on all subdomains. Our website has 5 subdomains: blog: wordpress store: prestashop forums: phpbb wiki: mediawiki support: ostickets You may modify the files in our testing server. But, at the end of the job, we want a zip file with all the modified files of each subdomain in order to reproduce the changes in the production server.
