Shelter4all needs an outstanding and clear website immediately Urgent Job

General information for the website: This is not a charity related website but has to have that appeal it is for a large viral campaign we are undertaking which has a lot of high profile and celebratory support.
Kind of development: New website from scratch
Num. of web pages/modules: 6 pages
Description of every page/module: This website is for people to show there support by uploading there picture and for them to get a clear understanding what the shelter for all campaign is about and what we are trying to do which is through the help of technology eradicate homelessness.
Description of requirements/features: This site is urgent so only developer who can start immediately. Here are websites I really like http://www.charitywater.org/ and http://www.macmillan.org.uk/Home.aspx and http://invisiblechildren.com/
We are looking for a really clean and low content site one that really details the issues and makes the campaign of what we are trying to do fun and innovative.

We want to incompass a lot of these images and really get the site to be one that drives people to act and make a difference.

It has to have a high technology, futurastic feel to the site. This site is the main headquarters for the campaign and even though we do want to push people to other business related sites we really want them to get a feel and understanding what this campaign is about.

It will involve a lot of photos of people participating in the campaign and will need to be designed and developed in an outstanding way. I need a really well designed site.
Specific technologies required: wordpress because I need it ASAP but any other options considered
Extra notes: We are a viral campaign with some very high profile backers which has supports from celebratory and charities and a lot of key organisations the expectation of our campaign and many in the press is that this site will be seen by 100 of thousands of people and be a main gateway into the support.
