How does one represent a sovereign citizen?

I learned today that sovcits believe that lawyers are some type of government agent trying to coerce you into contracting with the states, and we are under a common wealth, hence why the BAR is actually the (British accreditation registry.) If all of this is true, then how does a sovcit find representation? Do they have a U.S. accreditation registry that use? Also who bills who? Do they bill each other?
