I don't know that you'll be able to find anything OTHER than feeds for what you're asking. That or custom content of course.
I'm also interested in responses to this thread, so I can send some clients the way of someone with GOOD content, if they don't want to lease it.
If you can't find anything good to buy mate, drop me a line and I'll shoot you off a demo pass to
www.pluginfeeds.com
Hell, hit me up anyways and you can check it out.
