I spent a few weeks looking for places to sell my content to. Resellers, who would offer either a percentage or a set price per set. The thing is, the percentage was usualyl about 50% (sometimes less) and the price per set wasn't great. In a week of selling my own content non-exclusively, I have made more money than I would have gotten selling the exclusive rights to *half* of it to a reseller.
There are a lot of sites out there that will link to content providers, even small ones. My advice is to put together a license, and a web page about your content, to advertise it to webmasters. Then submit to a bunch of webmaster resource sites.
It's late, so I don't feel like listing a ton here... On the right side of my content page at
