Adobe Muse to Regular CSS (Dreamweaver)

Need to convert an Adobe Muse site (one page Squeeze page) to regular CSS. Love the easy design of Muse but the output HTML is bugging. Errors. Pretty sure it's a conflict between Jotform and Muse. Don't want to mess with it. Please see [login to view URL] The output files/folders are standard. In the root there's [login to view URL] and an xml file + 3 folders: images / css / scripts. Need to center the whole site and reposition everything as is down to the graveyard shot and tidy up the 3 options at the bottom. Lightbox gallery needs to be added to 2 of them. We'll provide the graphics, the jotforms and the Youtube addresses. Thank you
