This is a commercial project for the city of Memphis. My GC refuses to pay for damage that his subs did to my work, I am a specialty lighting fabricator. I sent him the bill and he refuses to pay. He admits to the damage but says that my price is arbitrary.
You can file a lien if you filed your notice of lien rights on the project with the Secretary of State. If you did not file your notice, then you have lost your lien rights. You still have breach of contract rights and could sue the GC for the amounts owed.
