How to find clients interested in Elasticsearch?

Elasticsearch in principle offers a lot of potential, I really like the result and fast interactivity but finding the exact cases where that volume of data is necessary with a client willing to support it in a production environment is difficult.

All I found is a few full time positions. It would be great if I could find a client/startup that would accept a contract position to build with Elasticsearch in a dev environment.

the ideal use case would be a large volume of data for few users.

I have other projects that I am working on, and I'm looking for something more flexible than a permanent position.
