Convert Website to Wordpress Theme

I need the following website converting to a wordpress theme. [login to view URL] I had been considering using this free theme as a starting point: [login to view URL] Currently each main page has its own header image, this feature is to be retained in the wordpress theme. There is a variable / function within wordpress that allows you to interrogate the current page, so it is a simple matter to do this (though I cannot remember the name of the variable / function off hand). Threaded comments must be supported by the theme. A contact page is also required, I know there are plugins that can do this, but I would rather have a contact form included in the template. I need all artwork to be preserved. We want to retain a "soft" informal feel for this site and are not looking for the typical kind of CSS work seen on many other sites. Essentially, the feel and character of this site is to be retained in a Wordpress theme, with some "tidying up" being done along the way. Of course all email addresses etc. will be removed when contact form is added. As this template is already quite close to a WP layout anyway I do not expect it to be problematic. One feature that would be nice is to make the grey banner to the right hand side of the homepage administerable via the WP admin console. I would be open to suggestions on a solution for that if anyone has one.
