NRES National real estate solutions Ignore email pay requests and not wants to cut our payout thousand oaks California

We performed a rehab at a property here in Pennsylvania. Our agreed payout was already below market but signed on thinking we could build a healthy business relationship with NRES (National real estate solutions) But since Day 1 the agent responsible for the property made it clear that he wanted his pal to get the approval for work so it was all up hill from there. He found some of the most minor issues with everything to the point we agreed to walk away and the changes be made by another contractor. At this point we were 95% done so no way in hell we thought our $18k would be cut down to $3500 for changes and penalties.....at this point I just want to take them to court because after reading all the reviews they do this often so now its about the principle. And they have the nerve to still contact me to do more work orders. I am looking for the right attorney to take my case.
