I was doing some research on the geology surrounding my house when I happened upon a geomap of Seattle from the UW. In the article one of the references mentioned was for a company called Aspect Consulting. I called them and spoke at length about my project. They were very helpful and while I ended up not needing to use their service, the fact that they were willing to help me even though I was not a client made me bookmark their website.
This is their site:

You could call anyone of their clients and speak with them for a reference.
