SmugMug Customization -- 2

Hi! I've a SmugMug site I want to make some changes on. New template, and some minor customization, on the theme and gallery sites. I believe all can be done inside SmugMug's settings. The first SmugMug customization I did myself in about an hour, following a YouTube tutorial, and I got the site as I wanted. But when trying to change it for the new look, I messed up. I've the site, content, logo, and the idea of the look I want. The attached screenshot is very close to what I want. For some who is very familiar with SmugMug, it shouldn't be more than a couple of hours work, probably less. I don't have all the details, so there will be some communication during the work prosess. NB: You must have good knowledge about SmugMug. If not, please do not make a offer!!!
