Full website for an upstart Political Action Committee

Our goal is to start an organization to raise money and awarness for candidates and causes that support federal campaign finance reform. I need a site that will allow me to easily share information about our mission and ideals with a easy CMS back end. The time frame I need is fluid so I can work with your schedule. I don't have an exact idea of how big the site will nned to be but I can provide examples of similar sites to interested parties and we can work out the details together.
