Semantic Search is free software licensed under the GPLv2. You can download the software and use it, as well as submit bug reports and feature requests, at http://drupal.org/project/semantic_search. The software is provided WITHOUT warranty and is currently alpha quality.
Some feature requests require significant development time, and require funding. A number of features are planned which would benefit from financial support. New features will be folded back into the open source code, so this support will benefit the Drupal community and the larger internet community.

Consulting services and customizations which use Semantic Search, are also available, including but not limited to:
The rate structure is as follows:
We will also help to support the development of other RDF stores on which Semantic Search depends. Including ARC, YARS, and Sesame(OpenRDF). A discount rate is available if you help the development of these or another RDF/Triple store. Note: you may find that these RDF stores are already feature complete for what you need. They come with HTTP RPC front ends, are quite efficient, and integrate into JAVA and PHP web environments out of the box.
