choppy:- Taking a Yid to arkoyos (goyish court) is a massive aveira.
I think that you Choppy are living in a dream world. In the ideal world you would be right, but in today's contemporary society, Beth Din is not even an option. Lamentably, they are corrupt thru & thru, and time may also be of the essence.
Do you Azolis belong to a Union? If so, your union may have a lawyer at a very reduced rate.
You may also wish to study the very 1st Mishna & accompanying Talmud in Bobo Basra, which discusses this very topic & issue.
With Parshas Ki Sovo literally around the corner, there is only 1 massive Aveiro that I can think of, and it is certainly not going to Arko'us, but simply being "Masig Gevul Re'Eihu" which is 1 of the 11 or 12 curses in Ki Sovo, depending on how these 11/12 curses are counted.
Failing that, you may wish to consult a professional mediator or binding arbitration.
