How do I collect money from a general contractor who will not pay when we only had a verbal agreement?

Question Details:

I am a subcontractor that just completed a big job in a neighboring town. The GC I worked for and I have a contract for a set price on siding. During the course of working I was asked to bend my own metal and among other things that weren't on the original contract. I was told to submit a bill at the end. The GC agreed to pay for somethings like metal - normally done at $3 a ft; I asked for $2 a ft; he only agrees to pay $.75 a ft. But other things I did that had to be done in order to complete my job he won't pay for. What can I do? Someone told me a lein, but he doesn't own the building.
