Need help with Search String

[Jamie Stout]

Good Afternoon Everyone,

I am in a little pickle here and need some assistance.  I have been asked to identify a specific list of competitors for a search we are working on.  Here's "the pickle part" I have been given part of each competitors name.  The industry that this mysterious companies are in is Healthcare Billing for School Districts.  I have tried:

 "healthcare billing" AND "school districts" AND paradine* and many variations of string.  Ii have tried insiter searches on linkedin and come up with nothing.   am sure I am missing an operator that could be very beneficial to the results of my search.  Thanks so much for the help
