CEFEMAC Website (request for quotation based on Template)

I will like to create a website for my organisation and will like it to be based on the following template:<[login to view URL]> It will need to embed videos within the website, section for gallery, dairy for prospective benefactors of the organisation sharing their experiences, sharing options with facebook, twitter etc and a calendar for events asshown on the screen. I will prefer this to be done in HTML 5 using the template which I will purchase eventually, but will require some modifications in the colours and layout to some extent. I will like it to include a Content management Platform that facilitates updating of the site.
