It appears the cMap template would suit your needs quite well. The layout is a little different but overall it is pretty close.
You can remove the gradient background from cMap, see this doc page.
re: Premium sponsors are highlighted and have a logo on both the directory listing and individual pages.
If you do not add a logo to an entry, none will be shown. If a member is no longer a premium sponsor, you can either remove the logo or set the logo not to be displayed.
re: There are 4 levels recognized on the member directory page by highlight: Platinum, Gold, Silver & Bronze (no distinction between levels here).
If you choose to set these apart visually, you can do so with some CSS by creating a custom CSS file for the template.
re: However, logos are also used in the sidebar (Platinum & Gold are always shown, Silver & Bronze rotate).
There’s nothing available that can do this “out of the box”. Since these are just categorized entries you could custom code a widget.
Hope that addresses your questions thoroughly!
