Full site (minus content)

I need a website built on an unmanaged cloud hosted server with dedicated ip, the site will need to have 2 parts fully integrated with each other: a community that connects profiles with games and the games themselves in the form of html 5 apps. Also the apps will be ported to mobile (not part of this project) so the mobile version and the website still need to work together. You pick the CMS. Cloud i believe can be linux or windows, so if you prefer or recommend one OS over the other please mention it in your bid. Website needs a full community build (ie. User profile, game stats connectivity, funds/wallet, website high scores, etc.) And the site itself needs to seamlessly integrate html5 apps (games) into the website, both display/playing in the browser and mobile app connectivity to all the same parts of the website (for security/integrity, profile, stats, funds, etc.) that the browser versions are. Social media also needs to be integrated into the website, as it is integrated into the games as well. A forum will also be needed. Please reply with which CMS you will use. Keep in mind, your bid is for the whole project, which is all the work of creating the website minus the apps and images and content. Front-end and back-end, including all systems for connecting/tracking profiles, apps, stats, and funds, as well as displaying them (eg. Within profile, within 'high score' top 10 modules, etc.). This is not a rush job. Thanks for considering my project!
