Where can I buy some good quality soil for raised beds?

I'm adding a 4 more raised beds this year, and need to buy some soil by the cubic yard. Last year, I had too much compost and not enough soil to mix it with. The result was so porous, the water just ran straight through. I plan to mix the contents of those beds with a higher ratio of soil. Can anyone recommend a source where I can buy good soil around the South Sound region? I'd prefer that it be more soil than compost. And I'd like to buy organic if it's affordable. I appreciate any suggestions.
