Joomla site conversion

We want to convert our website to Joomla for a more cleaner look and ease of maintenance (and content creation/change). Current website is at [login to view URL] We would like to keep the overall color scheme and general ease of navigation, but want some consistency through the site and are open to change. We can provide our own graphic design and flash work where needed, but the overall goal is a clean look which will also be more search-friendly to supplement our new marketing campaign. Additionally, we want to create a one-page HTML template (non-Joomla based) in the same design spec as our site to be used as landing pages, email blasts, etc... For other Joomla sites in our field that we like (to give an idea) see [login to view URL], [login to view URL], www.ftgroup.com. We are not looking to copy them, but more to give an idea of the clean, professional, and manageable look we are going for.
