facejob on existing site

I have a adult picture share website/image uploader site that is off a free script. I want to save my files already in place and keep all images. I am going to redirect site to another domain so I want to make this site look a bit more unique and optimize the ways to ad ads to make more money. i like the way the ads already show on the viewer. i so not want to lose ad space.I would like something very user friendly. I am a newbie to websites and desire something that I could work with. If freelancer has an Idea with a free joomla template for the site. I will be willing to hear it out. And if there is another free script better then the one I am using and I could transfer all files then I might be up for it.
