We spent several years volunteering at various places. While researching these jobs we found that most of the State parks require the volunteer to clean bathrooms. Not for us I'm afraid. However we also spent several seasons at Army Corps of Engineers campgrounds and the janitorial work was contracted out. Also we spent a couple of seasons in National Parks. Great times. Research Volunteer.gov and select states you are interested in. Can't help you with the fingerprint issue sorry. Both of us have ours on file. And no, not criminal files lol.
