Looking For A V3.0.6 Responsive Theme

Hi All-

I have a client running v3.0.6 and doesn't want to upgrade but want's a responsive theme for his site. I found a theme at websiteskin.com that would work but I have been trying to buy it for months and their PayPal never works and they don't respond to any of my emails.

They seem to be the only listings in the Marketplace so I thought I would reach out and see if anyone else has any leads.
