44624 HTML Site to Custom Joomla

I am looking to convert my existing html website, [login to view URL] to a Content Management Site, Joomla ( [login to view URL] ). The site is a very very small site, not that big, only roughly 20-30 html pages. The most important feature that I cannot lose, is I currently have a PHPBB 2.016 Forum That has roughly 90 members and over 2000 posts. If it is possible to somehow integrate the current forum into Joomla without losing anything, than that would be preferred. Also, I would like to minimize the downtime of the website/forum during the conversion process (so I don't want the site to be unavailable to users for multiple days while it is being converted). Also, I want a fresh new custom Joomla template designed (not a rehashed version of what is currently available). Also, I would like a unique design, that is easy on the eyes but still has a cool newwave look to it. I am definately not wanting plain and boring. A few things to note: - I am wanting a complete new look. It should be a fresh, edgy unique look but be easy to read the text. As part of the new look I will need a new logo to be designed. - The design should take into account that the content will be on the various pages will be 60-70% composed of images. (see the pages on the current site to see what I mean) - I will need the source PSD files upon completion - I will also want to see a few examples of Mambo/Joomla Templates you have created for me to consider you for this project... Since the website is so small, I wouldn't expect the conversion to take too long.
