Save Earl's Court campaign web designer and content updater for official website

Hello. I am a member of the Save Earl's Court campaign. We have an official website www.saveearlscourt.com. We have a major event coming up on the 26 October and we need to create separate pages for this and we need you to be able to update content on our website quickly and also archive it properly where it is easy to read. We need a You Tube channel attached to the website where videos etc can be uploaded by you before our event and after. This job would suit someone who supports the aims of our campaign and community action. The job would involve lulls in activity and then bursts of activity at short notice. E.g an article about our campaign appears and we want it on the website so we can tweet the link etc. Starting date would be soon as we need our separate page and You Tube channel ready etc.
