That is an interesting point to make when you want to convince politics (at any level): free software entails a free market for support because any user can get the source code and pay anyone to implements new features, fix bugs, etc. The user does not enter a monopoly for support as she does with proprietary software and she can employ local fellows to get support.
I do not know the purpose of your question but, beyond the "big names" listed
on
https://en.wikipedia.org/wiki/List_of_commercial_open-source_applications_and_services
you can find small local business providing service around free software.
That includes service around LibreOffice (formations for instance).
