Design a Website Mockup - repost

I am an artist and I am looking to put my work up online. I have graphics experience so a lot of things like the logo and homepage background can just be plugged in to the overall website. I just dont have knowledge in HTML, CSS etc. Basically, the site would be comprised of 3 sections: 1: page of sketches (where I can upload my own sketches easily) 2: page of graphics (where I can upload my graphics easily) 3: page of paintings (where I can upload my paintings easily) 4: link to my tumblr page 5: link to a commerce page so I can sell my work. I already have a domain name bought, logo is done, and images are ready to be added. I would just like to get the project up in a nice, clean format that looks cool and enticing to the viewer.
