If I was making a change in this direction, here is what I would look for:
1 - contract job listings or small consulting firms that do data warehousing, ETL dev, and reporting. 2 - Mid-size companies in a specific industry that need this type of custom reporting. Financial services companies are immediate targets.
One caveat - my personal search has indicated that many companies are tightly (very tightly) bound to using a report solution from a big vendor (Sas, Cognos, MS, or Microstrateg) and will probably NOT deviate from that platform. These types of places view reports using a specific provider as a very good thing seeing how they can hire report devs with that exact skillset when they need new reports or additional data sources added in.
This vendor tie-in extends into ETL tools (eg, you'll see lots of job requests for Informatica or AbInitio skills)
