DAMA Phoenix website conversion from PHP

We recently had our non-profit website [login to view URL] redesigned in PHP and changed host to 1and1. We want the site to be simple to maintain. We want a bid to redesign all the pages and script to plain HTML eliminating all PHP pages. We realize some existing functionality may have to be simplified. In addition, we want a recommendation on whether we can use the free 1and1 WebSite Builder or the $9.99/month WebSiteBuilder Plus.
