I have been looking for a free/cheap wordpress theme which is a one column theme, with all the links in the footer. I also want to be able to have a shadow around the main body content. This is for a blog where the blog posts will consist of a few large images which are the width of the main content.
I have had a look but can’t seem to find anything which totally meets all these. Can anyone suggest a theme or a site which has a good searchable list of themes.
You won’t necessarily find a theme that does everything you want, but something like a shadow can easily be added in yourself (with help from here if needed). 
You can try Thesis theme .
